Poor service - devices fail spontaneously after time.

Poor service devices fail spontaneously in storage.. AVOID We have two readers. We use them infrequently. I powered them both up today and they both failed with a tamper warning. Support suggest they had been dropped - but they were both used in different places and put away carefully a box working. Clearly there's a bug in the software - perhaps related to the battery discharging fully. They have not been dropped. They just said they were out of warranty - I will try for small claims court ...

Bad customer service !!

Bad customer service !! First, you will be greeted by a computer system, then if you can’t get an answer to your query an operator will steps in. You’ll think : finally a human ! Nope, they are Not helpful at all and gladly STOP the conversation at any given time when annoyed (?)! They’ll disappear. Which equal to “put the phone down on you”. I tried 3 times to ask the same question today.

The crapness of SumUp. The card reader for sum up is slow

The card reader for sum up is slow, really slow. I'm an ice cream vendor & by the time the card reader has gained Internet access the customer is usually wearing the goods. This product is clearly not good enough for outside mobile trading. The fact that it can take up to 4 days to reach your account & they charge 1.5% for the privilege is frankly an embarrassment. Use cash in future

Very poor customer service

Very poor customer service Have been using sum up since the past 4 years and recommended their service to other businesses. Following a "Device is blocked " issue, I sent an email to customer services on 12/06/23 and received a reply that I would receive a replacement machine as it was still in warranty. They took our delivery address and confirmed that a replacement would be sent out. The following day on 13/06/23 received an email from a different person that the device was no longer ...
