Telkom is a joke.... you want payment for bad service

Since the beginning of this year, Telkom has failed to provide me with good service!!! when my line was installed, I immediately complained about the static noise on the line. I have logged numerous complaints to get the line sorted but to no avail. All this time I have put up with the fact that I am paying for something that doesnot work properly. On 26 Oct, the debit order was unpaid, this morning I get an sms to immediately pay, so I call the billing department to query the amount as it differs to the debit order. I get told, I must immediately pay Oct 26th and Nov 27th bill in order to remain connected!!!! What utter ******* is this....... my account is in collections because I missed one payment and you want me to also immediately pay something that is due at the end of November otherwise you will cut my service!!! If I could cancel my contract I would!!!! Service request numbers: ********** 6, ********** 0
