Extremely Unprofessional and Unethical

I had a sliding door glass broken found online a company called Tillys Glass Mate ,phoned them they asked me to take pictures for my broken glass so that they can give me a quote,I did that,they quoted me R1585 which I paid I full ,I have attached the slip.They came removed the one side of the sliding door that was broken to install it in their company,When they have to put back they said its going to be a challenge I have to look for someone to remove the buglar outside for them to put the door back,but they are not sure.Nonetheless i managed to look for someone to remove the buglar they said they won't wait for him they are knocking off,instructed the guy removing the buglar how to put the door in its easy,the drivers had attitude didn't even want to stay,left with their car,they left numbers if he struggles I should call them,The buglar guy removed the buglar tried to put the sliding door failed to install back,I phoned the drivers they said they don't have transport to come to my side,I took my car out to fetch him at De Deur because he's doesn't have a car,Long story short he tried to put the door back he also failed,even they sliding door was being disassembled,he ddnt even have tools on him.This whole incident happened on the 1st of November up this day they never came back. I have been calling the store the owner not is assisting-Mr Mohammed,says hes busy, there's a young lady who knows the whole story her name is Nisha working there but still they don't listen to her,The drivers names is Thabo and Sam,.I am stuck with the sliding door that is not moving and I paid in full they say they are busy,and I'm also a customer without safety because I can't put back the buglar before they finish -when this drivers arrived he said I was overcharged by the store,but still they don't do their work properly Just got off a the call with one of their assistants to say they knew the sliding door wheel were finished but ddnt say anything because I ddnt ask for that quote,the door was working perfectly fine before the glass got broken and removed by them and that the manager said they will never assist me.
