Worst customer service

Logged a complaint on the 8th of November was told turn around time is 12 to 24 hours only for it to get a response 48 hours later and I had to be the one who calls Mr Ruan to be told that we buy cars has agreed for them to pay. Supp**** we buy cars with the shortfall invoice at 09:47am on the 14th of November to be told that by close of business I should have the proof of payment 16:30 I call back yet again because customer feedback is not top priority I am told that account department has not sent the pop.
