Vodacom no signal - won't cancel contract

I have been a customer of Vodacom since 1996

Ou gate system was upgraded to an electronic system with sim card to open the gate. I naturally took a small extra contract attached to my phone contract so that we could operate the gate - we have a guest house and this is a much more secure system than remotes. It worked well, except that, many times, there was no signal and guests panicked.

I reported it several times, waited for weeks to be contacted and last year in October a technician came out to test. He said they would fix it, but it was worse in November & December. One regular guest promised to never come back to this guest house as she was late for her appointment. I have many names of guest who could be contacted because they have struggled with this problem.

This year, I decided to test MTN and for 2 weeks we have never had any problems with the MTN signal at the gate, the gate opens every time.

I have now requested to cancel this contract on ***. The manager at Cresta shopping Centre wrote a special request to the CEO's office, only to be notified after a week that the problem has been resolved.

It has not been resolved! I am not prepared to give it another try. I want to cancel the contract although I took out a new one in October. I cannot go through this again. I have had enough of struggling and being red-faced with my guests.
