No response on complaints... Ever.

I bought a 2007 1.4 Ford Fiesta from WeBuyCars on Monday the 17th of February 2020. I was assisted by Kyle (I think that was his name, he is still a trainee) and Clifford Witten. Both gave me fantastic service. We did a full inspection on the car (including an engine check, etc.). All was great and I took my new car home. En route home, my check engine light went on which is concerning as no issues were noted on the engine by any sales reps. I had a diagnostic run on the car and results told us that there is a misfire on cylinder 1. I spoke to Clifford on 18/02/2020 to report the issue and he advised me on 19/02/2020 to lay a complaint on the website. Which I did.

To this day I have not received feedback from WeBuyCars even though they guarantee a response within 24 hours on their website. All their phones are constantly busy as well.

Surely someone can at least make contact and tell me what the next steps are as we still have rights as consumers.
