Service failure

Service delivery is so poor. I got quoted for installation of a new alarm system and the sales consultant kept following up for me to make payment. I eventually put down a deposit and when i tried contacting him to follow up on the installation, he ignored my email and text, possibly because his commission was secured whilst i was stranded trying to find out what was happening. When i eventually called the call center i was getting different stories. On one of the calls, the call center agent linked me up with him via phone and he had the audacity to not take any responsibility for not responding to the mail or text ,but saying i should have phoned him, and began to relay information which could have been provided to me in my direct follow ups with him. Funny enough, he has time to send casual chain messages to my watsapp number which clearly have nothing to do with, installation of my system. Disgusting
