***** done with with my name at Telkom Mobile

I have a phone contact with Telkom mobile, and end of January i found out that they have opened another account with my details . And which i didn't even apply for , i just receive the statement and i was shocked to find out ***** was done with my name to open another cellphone contract. I took up with their ***** department, and emailed them the statements and asked them to explain what is happening. I have not got any response since February and they are now deducting more on my account, which the is no explanation for it. My contract ends this month i cant wait , cause if they are not sorting issue this month am taking it further. Am so angry cause this is damaging my credit profile and am paying for something i didn't apply for...
