PG Glass Edenvale incompetence

I called the PG Glass Call centre to request a quote for replacing a sliding door and the glass. My information was passed on to PG Glass Edenvale at the end of April 2018. Tshidi called me and I explained I want to replace the entire door (frame included) and she said she would send me a quote. More than a week later I finally received the quote. I was overseas at the time, so I only accepted the quote when I returned. The job was booked by Tshidi, but on the day when it was supposed to happen I was told tshidi is off and nobody knew about the job. Vasco, after first lying to me and saying that they have a sample of the glass - which they never collected) quickly arranged for somebody to come and look. They came late afternoon and told me the wuite I received was just for the glass and that they will do a new quote. By this time, I had already paid the amount nt quoted in full as is the requirement for them to do the job. I received a new quote finally and devided the customer service sucks, so I requested a refund. I had to resend a refund e-mail 10 times before I got a response. The response from Tshidi -here is a refund form. No explanation, no turn around time nothing. On Tuesday, 29 May 2018 I sent my refund form. I sent it 5 times because they did not bother responding. Finally it was forwarded to Anthony. I was promised that my refund will be done on Thursday, 30 May 2018 because I have had so much trouble. Needless to say, Thursday came and went. I called Anthony in Friday and he **** to me and said it was in the queue to be refunded and it will show on Friday. Obviously this did not happen. I suddenly received an e-mail telling me I must now wait for my refund until Tuesday, 5 May 2018 because Management did not sign it off. The employees and management at that store is terrible. They mak promises they can not keep and lie to hide their incompetence.
