Cellphone account *****

An amount of R1,543.28 has been deducted twice on my bank account by Telkom Mobile over 2 expensive cellphones I'm not aware of. Unfortunately I'm not the one that opened the account. I've been trying to get hold of them and I am unsuccessful. My biggest worry is my name being sent to credit bereau. None of Telkom Mobile rep has contucted me. I'm stuck with this problem alone. I've been sending affidavit e-mailing. They said the matter is with the ***** Department but their account section is deducting money. This will ruin my name and my affordability record. I need to see the records and signatures of a person that opened d account. I don't even live in Pinetown. Worsely I don't even own a latest phone. I need a letter that will state that they have remove my name under telkom and they must stop deducting my money.
