I am DONE...sssooo DONE!!! WILL NOT LEAVE THIS

On 17 December 2015 I reported a fault on my router and tel. line with ***. A technician was at my house for about 3min and left saying he will be right back. He didn't return. I then logged a fault again on 4 January 2016 with ***. Although I called in lots of times to get feedback after being on hold for up to 50 min at a time, no response was given and they transfer you from one person to another or tell you they will call you back and then they don't. I eventually escalated the case with ***. I kept on calling for feedback. On the 27th January 2016 I was on hold for more than 2 hours - same story. My calls were cut every time just before I could speak to Manager. I was billed for two months of Internet usage I didn't use, I was put onto ITC for not paying, after the billing department ensured me I don't have to pay while the case is still open. I had to go to a Telkom store to get my router fixed myself as Telkom was too useless to send somebody out. I am sooooo fedup with them there are no words... I can't even call them from my tel as it is not working and every time I need to beg someone to use their phone.
