Here at D&S Premier Leather I’ve had the worst experience ever with SumUp as a POS system. I previously used Square and was content until a SumUp rep persuaded me to switch. What a mistake. Their customer service is non-existent. Since Christmas, I’ve waited on a software fix that only just got sorted now—after endless delays. I lost customers because the machine would hang, and printing receipts took too long. After 18 months of frustration, they offered me a token £20 fee reduction—no real compensation. It takes three weeks for them to even respond to an email. While their phone reps are polite, they have no clue how to fix anything. Honestly, it’s appalling service from a big company that should do better. As soon as I can, I’m going back to Square. If you’ve had similar issues, give this a like or comment. SumUp has been a nightmare.
