2 months from payment and no security - let our weakness be your weakness

I paid Maxidor a 50% deposit on the 7th of August for my gates for a shopfront that were meant to be installed after 15 working days. I received a call on the 7th September to pay the balance which i did so that they could install the gates. Whilst maxidor was installing the gates i noticed that the entrance height was approximately 1,8 meters so i rejected the gates as customers would have to bend down to enter my store and asked them to redo at the correct height. Its now a month later and i still have no gates installed. Mark Dray the salesman made promises that were not kept and now does not take my calls. The branch manager Gavin promised installation for the 4th of October 2017 at 8 am which was not done. I received a call from Christen yesterday informing me that the gates are not yet ready. Today i received a call from Jody the "technical manager" to tell me that he is trying to find out more about the miscommunication and the reasons for my gates not being installed today. I do not have a date for installation. This is the worst experience i have ever had with a supposedly "reputable company". I am sure i will now receive an apology which i have received from every one of them contacted above but still no gates. When large companies ask for a 50% deposit it does not mean that they will deliver and when you pay the balance prior to installation it does not mean that the gate being installed is what you require..... You are then left with no recourse as the bill is paid in full and you are now at their mercy to get what you paid for. Maxidor your apparent strength was my security weakness..... I would never recommend you or use you again
