Perthetic After Service

The after service for maxidor is perthetic... I had it installed about 2months ago, and prior to installation the maxidor agent (Tertius Delport) emailed me almost everyday to get d sale... I placed an r80k order so it wasnt just 1 door... I have been contacting Tertious from the 23/02/2016 to have d guys cum out and chnge the locks to work with 1 key which we had discussed and agreed to do prior to installation, and to fix 1 door because it is loose(was not installed properly), the other doors are not 100% and i have to mernover it to close it, i am not happy with this product at all ... Tertius kept telling me he will sort it out, to date nothing has been done... I am not prepared to wait any longer as this is a saftey risk to my home... Please can u send some1 to remove these doors and deposit my money back into my acc... Regards Muhammed
