Most Pathethic and Ineffecient Service

I have had the most frustrating and exhausting interaction with Maxidor's after sales service. Maxidor is very quick to sell you their products but the after sales service is by far the most pathetic I have come across. I have Maxidor gates for almost 3 years now and when I need the required yearly service, which if not done voids the warranty then to Maxidor doesn't respond when trying to book a service. I have to either go through the branch manager or head office to get it done. And now when I had to have my gates removed and refitted due to tiling the area where the gates are, they charge nicely for removing and again for fitting BUT it is going to be 1month now that I am trying to get my gates refitted. I even spoke to the manageress on Friday 3rd July 2015 and still awaiting feed back. I called every week for the past month only to be told that they will get back to me but hence no call of mine has been returned. I did not want to resort to putting my complaint on Hello Peter but I think that this is the only way I will get some one at Maxidor to actually follow through with the service customers deserve.
