Poor service

Last week I had a booking 2 guys came out fixed the cambelt. They picked up that the cars wiring needs to be repaired ad the gearbox bolt needs to be replaced. I said fine send me the quotation. I received the quote made payment and booked for someone to come to me today. I received a call from a Chezlyn the one who was now supposed to come out today asking what needs to rewired. I asked him to speak to the guys who worked on the car last week he said fine. Only to receive a call saying that the guy was supposed to come to work on the car has an emergency but the guys who worked on the car last week can work on the car but I need to go to them. Not even sure where they located and why must I go out to them when I paid for them to come out to me. Now I have to wait 7 to 14 days for a refund not only that I need to send a bank confirmation letter so money can be paid into my account. They failed to reply to my email but I could receive 3 emails confirming the booking that was made and the payment I had to make. Now when they need to pay me no correspondence from their side. Absolutely disappointed in the service I would not recommend them to anyone. Very quick to ask for payment but when it comes to they paying us we need to wait 7 to 14 working days. No one who called me apologized for the inconvenience.
