Angry and disappointed costumre

I upgraded my phone last year in October that I waited for almost 3 months, my first bill for the new phone came and it was at least 3 times more, I was billed for something I didn't sign up for , second month came same thing happened, I was then promised that no deductions will be done in December by Nqobile from accounts, to my surprise on the 1st of January R 9 750 was deducted from my account of which I reversed then notified telkom, You can imagine the mess left on my in my account because of that deduction. No explanation was given to me but only that telkom couldn't see anything from their side, HOW POSSIBLE IS THAT? HOW UNPROFESSIONAL. Till today no one has come back to me to explain or apologized 4the ERROR on a month telkom was not even suppose to deduct . And guess what? I got my Jan bill, still SAME ERROR, I am still being billed for something I did not sign up for. I used to sing praises about Telkom, how disappointing is this???? Can someone take responsibility and fix this mess. Can someone fix the mess that was left in my bank account 1st day of the year??? Why do you ask us to rate you if you do not even follow-up on our ratings? Can someone please help!!!!
