Service cancelation due to the worst customer service in my life

Since my call on 9th of September advising supersonic I'm moving go a new place to this date 2nd October I got no assistance accept promises that they would transfer my line both monde and Joshua responded and called me after my numerous complaints on this site but neither of them ever bothered to call me again so yesterday I called again spoke to mbali I sed asked her is my line canceled at the old address seeing as this is what Joshua promised he will do she advised me not only was the line active but payment is due for both the old address and a new installation bearing in mind I no longer live at that address where they still didn't cancel and the new address the installation never ever took place now I'm being told to pay cancelation fees and give 30 days notice Nobody provided me a service I don't have wifi yet they already billing me they were notified in time as well. I will not pay supersonic one cent that transfer of the line I no longer want or need it as i due to them have been called bk to the office. Supersonic Staff have no idea what they are doing can't answer or help with anything and they say anything to get you off the line.
