ADT : VERY BAD SERVICE

Over a month ago, we had a burglary and contacted ADT and ordered additional beams. We paid the 50% deposit. Then we had the usual - no stock! Then stock arrived and they arrived for the installation. No, they brought the more expensive stock, which we refused. Said they would come back the next day. We are still waiting! Last Monday, 3rd, I phoned and was told I would be contacted! Still waiting - no call, so installation and if anything happens they won't take any responsibility!!
