Pethetic service / bad installations and theft

I got ADT out to replace a broken alarm sensor on my garage wall.<br> Firstly they left stating they need to order the product.<br> They disappeared for weeks and when I followed up they said they will come and replace the sensor.<br> They replaced it with the wrong sensor and the alarm lights indicating if the alarm is active is fixed with prestic!!!<br> I've been sending various e-mails made various calls to get them back to inspect the installation.<br> Someone came out, confirmed it was a bad installation and left, not to be heard from again.<br> 5 Days ago I received a sms stating that the outstanding money will be deducted by debit order.<br> This after I clearly stated that I will pay by EFT once I'm happy with the installation.<br> Today I received a sms from my bank stating that ADT tried to deduct an amount from my account.<br> If you don't sort this out in this week, I'll lay charges of damage to property and theft.
