Before you sign up to this company picture this please! You sell products to a customer who pays via a credit card using SumUp. A month later you realise SumUp have fully refunded the customer for no reason mentioned (not even an email, phone call NOTHING) nor has the customer notified you of any issues. SumUp are now NOT replying to any of our emails, not answering there phones NOTHING! We are now out of pocket for the sum of £450 thanks to @#£_Up. Awful customer service
