Very disappointed with the prompt payment to my dealer. Work approval very quick, work done February 5th, emailed invoice, someone called from company to the dealer to get VIN and by February 29th still no cheque. I contacted them and they said no invoice received so dealer resent March 2, they had dealer resend as blurry and Linda advised a cheque would go out in 10 to 15 days. Now March 31st still no cheque, called and they said would go out by end of week. No explanation for delay, no apologies!!! Very unimpressed with this company and will be letting Kia dealership know.
