Telkom *****ulent debiting my account

Telkom is debiting my account with R4717, we went to the telkom store at Mall of the North in Polokwane, they told me us that someone *****ulently open an account with my details and requested affidavit, ID COPY, 3 months bank statement and proof of address. We requested the information of the person who opened the account as requested by the police as we opened a case and We were told that they only have the address of the person and they were unable to provide us with the information. And they promised us that the matter has been resolved and they won't debit the account again. But to our surprise, Telkom has tried to debit my account again, despite written confirmation via sms on the 20th of April that case number: ***4 has been resolved. On the 3rd of May we received an sms that a Account customer *** has been suspended due to credit limit. May you kindly please assist with this matter please.
