No Customer Service Stay Away from Dynamic PVC Specialist

I contacted Dynamic PVC Specialist on 18 April for a quotation they were quick and responsive. They gave me an appointment to measure on the 20th of April and duly arrived to do this. I was provided with a quotation on the same day and within and hour signed it off and made full payment as Esther their representative agreed that she would arrange it for the 26 April "first thing". On the 26th they were a no show. I raised it with her via whatsapp and she promised to have it attended to the following day. I had arranged for my partner to be at home to oversee the installation so it was a massive inconvenience to have to ask him to work from home on the following day as well. I however arranged this. On the second day they were again a no show despite the installer messaging me in the morning to arrange this. Again I raised it with Esther and she apologized and promised to resolve. A promise that they would come on the 3rd day was made. At approximately 16H00 I called her to inform her that again her team was a no show. The installer then called me at around 17H00 to say he was on route. It was a long weekend and we were leaving for the weekend I informed him of this. I then called Esther to cancel the order. The installer messaged me and called me saying that he would be penalized if I didn't allow him to install. I asked what he proposed I do cancel my holiday to accommodate and installation at 6pm on on Friday that was originally scheduled for 4 days earlier at 8am? I was upset however resolved to cancel and just it a refund. Little did I know that this was only the beginning of my issues. I had no confirmation from Esther on my request for a refund. So I called her approximately a week later asking when I could expect this. To say that she was rude and unhelpful is a massive understatement I have several businesses and someone that represented my company in this manner would not see the light of another paycheck. I was horrified at her tone and unwillingness to resolve an issue caused by them, she spoke over me was argumentative and took my complaint as a personal insult although I repeated several times that I just wanted a refund and not to have to deal with them any further. Eventually 3 days later she claimed she had done her bit and submitted paperwork to accounts and could not do more than that. Eventually Vanessa from accounts called me. I explained everything leading up to my requesting the refund. She was very polite understood my position and undertook to escalate it and have the owner Mr Brown call me. An hour later she sent me a message from a WhatsApp business account saying that Mr Brown had left for the day. I respond saying I just wanted confirmation of my refund so I did not have to deal with her company any further. No response. I messaged again today 4 days later. No response. No call from the owner/manager. Added to this the installer messaged me saying that he could not pay his rent because they have no paid him as he is being punished for not being able to install my pool cover. Stay away from this company it is unbelievable in times when so many companies are struggling that customer service is not valued. I found them on face book - they seem to spend a large amount of money advertising, money that would be better spent on training their staff in terms of customer service. So no pool cover and no refund. I guess I will have to go a legal route and waste more time and effort.
