four months without internet

i have previously sent two messages on hellopeter regarding my 5gig internet data package STILL no resolution. Someone emailed to ask for some detail about an adsl line, i responded to say its not adsl its a wifi portable router and they just didnt bother responding. on the second review, someone called took the details and STILL no response. i have been without internet for going on 4 months now and even though i put a stop to the debit order, they STILL continued to take the payment somehow. This is absolutely ridiculous that i am still without internet and am paying for the service i do not have and my daughter has been kind enough to let me use some of her data (who is going to repay her for that?) and Telkom doesnt even bother to give me any feedback. the problem was that it said no service when i tried to connect, i tried it in numerous devices and it still did not work. they then sent the device away (which cannot be the problem because it doesnt work in other devices). i am EXTREMELY FRUSTRATED AND HAVE NEVER ENCOUNTERED SUCH BAD SERVICE IN MY LIFE!!! i want my money refunded and i want my contract cancelled as there are many other better deals out there and im sure i can get better service elsewhere. Also my daughter need to be compensated for my use of her data due to your lack of interest or service !!!!i dont know what to do anymore i am at my wits end!!!
