⚠️ Negative User Experiences (Trustpilot & Traders Union)
Across 13 Trustpilot reviews, Sardine Pay specifically faced criticism for reliability and support:
- Severe delays or nondelivery “They took 600€ and never give anything, just pure Scam” Trustpilot
“They will take your money and not deliver your assets. It’s almost impossible to reach customer service” Trustpilot - Repetitive holds on transactions “This is the 5th time sardine has held my crypto … they waited until the price went back up.” Trustpilot
- Unresponsive customer support “Support never replied… just sent me a letter with my own complaint back.” Trustpilot
“Customer service is non-existent—an absolute joke.” Trustpilot - Excessive fees and poor value “So many fees, bought 100 CHF of ethereum and received 87! feels like getting scammed!” Trustpilot
A separate Traders Union profile also notes a predominantly negative reputation, warning that it “significantly undermines trust” in the product Traders Union.
📊 Professional Feedback (G2 Reviews)
Despite high overall satisfaction, a few consistent drawbacks were noted by professional users:
- High complexity and steep learning curve
- Cluttered or non-intuitive UI
- “Complex UI design challenging when seeking detailed information behind metrics and scores.” 2G2
- Integration limitations
- “Need for better integration with ID verification … limiting efficiency.” G2
These cons are relatively minor compared to the overwhelmingly positive G2 ratings—only 4 mentions vs. dozens of praise—but highlight usability limitations and onboarding friction.
🧩 Summary
| Area | Key Criticisms |
|---|---|
| Reliability & Transactions | Serious delays, withheld funds, nondelivery – users accused it of being “scammy”. |
| Support | Reports of unresponsiveness, difficulty reaching real help. |
| Costs | Perceived high fees with poor conversion value. |
| Complexity & UX | Professional users note steep learning curve and cluttered UI. |
| Integrations | Some missing or limited third‑party verification connectivity. |
Overall, while Sardine is praised for its fraud tools and AML platform, the strongest negatives come from its Sardine Pay rails – particularly crypto on-ramp delays, poor user support, and transactional reliability. In business contexts, criticisms focus on complexity and UI clarity, though those are more manageable.
