Just transferred over to Tesco Mobile based on price. Got my new sim and tried to set up ! New sim wouldn’t work and so couldn’t make calls or texts ! Called Tesco on my wife’s phone to explain ! Went through numerous things to sort issue that didn’t work so they said they’d send replacement. After the phone call I tried a few more times to replace sim and suddenly started to work. Literally 5 mins after speaking to Tesco I called them back to explain issue had been resolved, sim working and my old number to be connected in two days ! All good ! Now Tesco tell me that they won’t cancel new sim, they ordered 5 mins earlier and so now will stop my service in a few days and will have to go through all the same again and try to get my original number for no reason at all ! Utter stupidity ! The staff I spoke to refused to do anything and basically said “tough s##t” been with them a day and already realised just how bad their customer service is ! To cause an issue that doesn’t exist and annoy a customer is utterly crazy ! Terrible service !!
