Review BAD SERVICE KIA RANDBURG

Dealing with the Dealer Principal Renaldo Singh from Kia Randburg comes with great disappointment.
I purchased my Kia Rio from Kia Weltevreden 4 years ago, from then the sales consultant, Renalado.
I approached Renaldo in selling my car on the 22nd July 2020 , of which Renaldo requested that I bring my car through for an evaluation/offer, we confirmed a price and he promised they would send through the evaluation by that afternoon so that I could send this through to the bank to start the process so that the bank could contact Renaldo.
I have been waiting since the 22nd July to yet receive this info.
Following up on numerous occasions with Renaldo, excuse after excuse and the promise was to send the info, still to no avail, once again following up .. the response yesterday 27th July "Hi Ann. I'm really sorry and I'll get it sorted".. still no feedback or evaluation/offer after saying he will get it sorted I called today 28th July .. not acknowledging that his service is bad and getting upset with me because I've queried this, now retracting and saying he doesn't buy cars and he has more important issues that hes running around with.
Please to note* not once did Renaldo make contact with me since the 28th July, I have had to follow up continuously.
Kia has just lost a client !! My Son was going to go and see Renaldo with a view to possibly purchasing a car.In other words 2 clients lost and more..
Really disappointment, in these times clients are all important doesn't matter how big or small they are. Even if they might not win with a deal right now, they should think long term for a potential future deal.
This is not the kind of service that I would expect from Kia and most of all not from the Dealer Principal.
