NO SERVICE, BUT STILL BILLING !

I logged a faulty line a month ago (this is the second log, my line has been off for 3 months) ********** (they are welcome to check) till today nothing has been done. I have now once again received a bill to pay my account which blows my mind as I do not understand how THEY are billing people for services not received, seems a bit ******* if you ask me. I am now ready to report them to the CPA and Onbutsman and also looking at my legal options. I am getting NO JOY from calling their call centre and I will not be wasting my time any further on that. I had three question that none of their unhelpfull staff could answer. 1) How are they planning on crediting me for 3 months of no service received 2) WHEN IS MY LIBE GOING TO BE FIXED?????????????? 3) I wanted to change my current package to a different package where I would be able to get a faster line with more data per month. I am really at my witts end with THEM and will not be making any further payments to Telkom.
