I have used RAC vehicle checks multiple times. I tend to buy the multi-check due to the frequency in which I require vehicle checks. On my latest use, I was confident I had at least one valid code left from my previous multi-check. With this confidence, I went to purchase a new vehicle for myself. After looking the vehicle over and decided to go ahead and purchase, I tried to use my remaining multi-check code. To my disappointment, it did not work. I therefore tried all of the other codes to ensure I was using the correct one. No luck. I then tried a different browser and a different device. Still no luck. I tried to contact customer service but received no reply on the phone as it was a Sunday. Not a valid excuse if the vehicle check service is advertised as 24/7. I had actually emailed 15 hours prior to attempting the check to ask which of my codes were valid but received no reply. At this point I was in a difficult situation as I needed to do a check on the vehicle prior to purchasing. I thought because the system rejected all of my codes, I must have been making a mistake and had actually use them all or they had expired. So I purchased a further multi-check, it processed, took payment and I received my check without issue. However, the following day I then received an email stating two codes from my previous multi check were in fact still valid and they had not processed when I initially tried due to a technical issue with the website. To this I replied respectfully asking the additional checks I had purchased to be refunded as they clearly were not required. Unfortunately RAC’s customer service clearly were not interested and showed zero respect to a loyal customer. They offered absolutely no support or means of remuneration. They happily took my money, despite it being essentially a duplicate purchase because of their IT failure and then essentially said it was my fault for purchasing a vehicle on a Sunday. Really disappointed with the outcome. I will not be using RAC’s vehicle check service again and I will ensure my experience is voiced to all that it would interest until I receive a refund.
