Dissapointed first time buyer

I am writing this with such disappointment. The We Buy Cars Brand is well advertised as being convenient and a place a person can come and purchase a car that is trusted. It is such a shame when poor service from the employees on the ground sabotages a brand as such has been my experience at the Port Elizabeth Branch. I purchased a Renault on the 22nd of March 2022. Impressed with the Dekra Condition Report I drove from East London to Port Elizabeth to go and purchase the vehicle. On arrival after 5pm, (arriving late as the car had a hold on it by staff and was only released after 10am after I called the call centre) the process begun. The Sales Rep who helped us told us we were very late and that we had to ensure the cash was paid in before 18h00 as his Manager would not allow his Admin staff to stay longer than 18h00. He rushed us through the whole procedure repeatedly reminding us that we would not be helped after 18h00. When I requested to speak to the Manager he told me that he was not there but said that his Manager would say the same thing he was saying . I merely wanted to ask the Manager why he was saying we would be kicked out at 18h00 yet we were customers who were in the store making a purchase but the Rep denied me to speak to his Manager. After being rushed with paper signing and all…. We discovered upon further I section of the vehicle that the apparatus used to remove the cover so we could access the nuts and the tool used to access the spare wheel were not on the car both not disclosed. It was already dark and we were driving a distance back to East London (3hrs) and could not risk not being able to change a tyre. After a long wait a mechanic came and forcibly took out the covers so atleast should we have a puncture on the trip home we could change it. When I was given the diagnostic report I found there was a fault for the central locking which was not working which was also not disclosed. On asking the Rep told me that cars at we but cars were sold as is and that they were a retailer. I agreed with this but they had to disclose all the things that were not in order and not hide them. I left dissatisfied and drove back to East London. On the drive back the cluch smelt most of the way, and it was written on the back of the sign they left in the car….all these faults were there but not disclosed. Weeks later I speak to the Rep asking how do I access the voucher for roadworthy from dekra he said I can only do it at PE and that if I do it there in EL I will need to send proof of payment and they will do a requisition and money will be paid back I to my account someday. Then the invoice sent by Dekra was not sufficient, I sent a second one which he only looked at a day later and still not sufficient. Reported this via the call centre and asked that they tell his Manager I was told the Manager would call me in 5 minutes and still nothing. Called the call centre again and still Manager did not call me back. How I can call as q customer to complain and not be called back is such bad customer service. Basically my complaint is being disregarded. Still documents sent on the 12th of March 2022 at 17h00…. The refund has still not been paid. After this poor service and being so undermined I could never recommend the brand to anyone elese. They do not respect the customer at all and do not have good customer service. And it’s bad for other branches who work hard and are now being let down by others. The worst part I get called by a company that does the warrantee for We Buy Cars days later…..offering me warrantee. I’m in disbelief because the sales rep I dealt with told me they only offer monthly warrantee to those being financed and that cash buyers like myself have to pay over 9000 cash and warrantee will only be offered for 6 months. This lady tells me I can get warrantee I can pay monthly for 2 years. i couldn’t believe it. I need urgent assistance on the refund matter or advice please.
