Telkom in the light of *******ion

Telkom handed our account over for collection on 1 May due to NON PAYMENT of account. According to my records, the account is paid every month. They have never notified us of such incident. The first we got to know that was on the 21 May via sms when notified of Impending Litigation. The number on the Notice does not appear anywhere on our statements sent to us, which is ********** 68. When I queried that, I was told it is the correct account number and the number I have on my records is only a Financial reference number. In other words, for a year I have been paying a wrong account??? They are so ******* and ***********, they don't even realise it.
