Been billed for 5 months after requesting line cancellation!

I requested a line cancellation on 27 October to be done at the end of November. I did everything right. I gave due notice and did not have a contract with them. They billed me for December, January, February and March! This after I called them in December to make sure they had now in fact canceled it. Their call centre did not even know about the cancellation request that I had submitted 2 months prior to calling them about the issue, this even though I had the reference number (which I saved because i suspected their incompetence would result in this exact problem).

Still struggling to have the line cancelled and for them to stop billing me. Don't know what to do anymore. Their call centre does not get anything done and they simply don't seem to care that they are literally *****ing my money.

It is now the 5th month they've billed me, the bill amounts to R2200 by now. This is just ludicrous. I refuse to pay for a service I do not use and is not being rendered.

Very very unhappy with their service
