HANDED OVER TO DEBT COLLECTORS BY TELKOM

I am really annoyed with Telkom Mobile. Due to them not keeping their house in order and lack of communication, I was handed over for Debt Collection. A company by the name of Nu Debt Management called me yesterday informing me I was in arrears on my Telkom mobile account even though I settled my account last month. I had to send them proof of payment confirming this. Despite doing this, I still get a SMS stating I am in breach of my contract due to non payment. I phoned Telkom's customer care & they informed my account was up to date & couldn't understand why Nu Debt Management contacted me. What really irritates me, since taking the contract, my bank account has not been debited by Telkom despite me confirming my banking details with them over 5 times. Every month I must phone in and find out why my account has not been debited & make manual payment. What's the point of asking for my bank account details when you don't debit my account? Because of Telkom not updating their records & lack of communication, my credit rating is at risk. TELKOM really needs to catch a wake up & sort this problem out once and for all.
