Cell tygervalley poorest service ever

The worst service ever . I've never made use of Cell c before as it my first time I'm very disappointed and didn't expect such incompetence. I've signed up for the samsung galaxy s21 on the 25th of February 2022. I asked of there's any indication fee that I must pay up front I was told no nothing by Shari Kieviets . As the battery was faulty and it was send to repairs on the 2nd of March 2022 , the device was handed in was told in will get the device back on the 11th of mach 2022 as I came there yet to my surprise no decive as RAM didn't come yet according to Lauren as she told me if I want to reduce the installment I can pay it via the cell c app .Cancelled the contract on the 18th of March 2022 . However another debit order went off my account and I ask for banking details for the so called data I've used as its a data and phone deal not only date I'm still liable to pay until the 7th of April 3022 which doesn't make sence. Made a partial payment then for some reason I was told by Shari that I wasn't suppose to do that as there's no trace off the payment , on the 2nd of April 2022. Until today I still didn't hear anything back from tygervally cell c
