non-performance

I have had major issues with cell c signal at my office in Olivedale. I have logged my first complaint last year. I was told that if I get a fibre line then cell c will come put a booster aerial at the office because I have 5 staff on cell c as well. Obviously that didnt happen. A few months ago someone called me and gave me vodacom settings for my cell phone and I got an sms saying my signal issue is resolved when it wasnt. If I leave the office I have to change the settings back on my phone or I cant get or make calls and I am on the road alot so in and out of the office like 20 times a day sometimes so changing settings all day long is not resolving the issue. The phone also continuously beeps on those settings which is very annoying. If I dont get the small booster aerial then I will be canceling my cell c unlimited contract next month when my upgrade is due. The rest of my staff will follow in the next 6 months as their upgrades are due. I have cancelled my fibre line to my house today with cell c as well due to them not sorting out issues where I am not getting any wifi signal at times.
