********** Cellphone contract opened in my name

My account was debited on the 1st of June 2022 with a cell c reference. I called my bank and queried. I was informed that this is from cell c. I then called Cell C and was informed that a cellphone contract was **********ly opened in my name. The consultant informed me to get an affidavit, along with a copy of my id and proof of address and send it to ***. I sent the 1st email on the 2nd June 2022. I have been sending several follow up emails, but there is no response. Today is the 1st of July and again cell c is trying to debit my account. I am out of the country and can only communicate via email now. This is absolutely pathetic that I keep getting billed and no response from cell c at all
