ADT knows nothing about good service

In order to enlist ADT as my security provider, I had to sign a two year contract and I haven't been happy with it for a single day. Every time they have been called out they refuse to do anything that doesn't involve a lockbox. so they just sit at the gate doing nothing.

then I asked them to install beams at least, which they said had a waiting period of several weeks. Then I asked them to service the alarm because it went off once unnecessarily - which they refused, and instead sent me a bill for R550 for 'excessive response' when they didn't even come.

At this stage, I never want to have a relatinoship wtih ADT again and I insist on cancelling my contract without 'penalties,' as terrible non-service is most definitely a breach of contract on ADT's part.
