Users consistently report customer support is a 'black hole.' Multiple users sent 6+ emails requesting refunds with zero response after 5+ days. Support tickets go unanswered for weeks. VentureBeat and multiple Trustpilot reviews confirm this is a systemic issue, not isolated incidents.

Users report being charged after they've canceled subscriptions. There is no cancel button - you must manually switch to 'Basic' plan on pricing page to stop renewal, which is completely confusing and arguably deceptive. Multiple Trustpilot and Reddit users call billing practices 'predatory.'

Monthly subscription credits do not roll over to next month. Users who don't use their full allocation lose them entirely. Only additionally purchased credits (beyond subscription) never expire. This catches users off guard and wastes subscription value.

When upgrading to watermark-free version, work is still watermarked. Retrying a render (which is common as they often fail or come out wrong) costs 100 credits per attempt. Users burn through credits rapidly just trying to get one usable output.

Features like image-to-video ('Pikaframes') are frequently restricted to paid users. Free users wanting to demo before committing can't properly evaluate the platform. After just a few free generations, users hit 'video failed to generate' walls unless upgrading.

Users subscribed to yearly plans after seeing ads for 'unlimited video generation with HD quality and no watermark.' The '10 videos per day' limit for AI generation isn't clear upfront. Users feel deceived when discovering actual limits.

A recurring highly negative complaint is the persistent 'High Demand' message leading to extremely long wait times - hours, days, even months - or generations never completing. Users who paid for credits find them essentially unusable due to perpetual queue delays.

Users frequently encounter technical roadblocks with AI models getting stuck during generation, often appearing frozen at 99% completion. 'Generation failed' and 'error during video processing' errors waste paid credits without producing usable output.

Where Pika falls short is post-production - tools are still too unpredictable for final delivery. Outputs aren't consistent across shots, details break under pressure, and longer edits aren't reliable. Described as 'feels like two completely different products.'

The experience is 'all over the place' - one minute you create something impressive, the next a glitchy unusable mess. Pika doesn't understand physics, logic, or how objects interact. Ball bouncing like lead, arms bending impossibly. More variation between runs than competitors.

Pika has a habit of ignoring instructions - write a detailed prompt and it disregards key elements. Users report asking to keep backgrounds the same but Pika changes them anyway. Infuriating when trying to maintain brand guidelines or specific creative vision.

Motion sometimes looks amazing, other times slightly off - especially with faces or hands. For cinematic realism or emotional storytelling, results are inconsistent. Pika shows more physics glitches than competitors' subtle errors.

Base resolution of 720p feels dated compared to competitors. Even 1080p on paid plans isn't 4K. Users wanting high-quality output for professional work find the resolution limitations disappointing for a premium-priced service.

App Store reviews report the app is temperamental when generating videos, with increased freezing during the generating phase. Some generated videos will not download once created, wasting the generation credits entirely.

The app blocks certain language as 'severe policy violations' without providing feedback about what triggered it. Prompts that worked previously get blocked on subsequent attempts. Users can't learn what's allowed because rules seem arbitrary and inconsistent.
