Pathetic service for a Pathetic gate

The maxidor lock has jammed. I logged the call on 17th Dec 2015 & until today 19th Feb it has not been fixed. I had to follow up with the call centre for over 2 weeks & it is still not fixed. As per the tech who called in Dec, they DONT WORK IN DEC & will ONLY COME OUT IN JAN! Really !Is that the kind of service offered. Jan came & went, no one called or came out! I started calling in Feb & had to shout so many times before the tech Tusani came out. Then i get told the gate isnt covered even though it was installed in 2012. He leaves & I have to call the call centre again to fight. He then calls last week & says he will come out on Monday 15th. Still didnt come out. Call him & he says that he is busy and we must call him at a different time so no customer service there. Called him again & get told that there are still 3 days left in the week so he doesnt know if he will come out I must just wait. Call the call centre & promised a call from Lynn - no feedback. Today i get told that Lyn has left - so didnt bother to complete my query. Spoke to Jermain today and still waiting for him to call me back however he has left as management leaves @ 3 although to me COB is 4h30! SO FRUSTRATED
