Poor Workmanship Costing the Customer

I had my Trellidor installed and had trouble with the gate from the get go but was told that my door not being the standard size nothing more could be done. Then in the week of 15 June the gate couldn't close as the gate & frame were not aligned. I was told to pay R500 fee. A week later & the gate is again out of alignment and won't close and I am expected to pay the R500 again. Poor workmanship followed by poor customer service.
