Called at 6pm & waited 2.5 hrs for patrol vehicle. Problem with coolant. Found to have a slight leak. Topped up with water & advised would be able to make my 100 mile journey home but would have to stop frequently to check coolant reservoir level & if necessary top up with water . Did as advised & stopped at garage after 20 mins. Could see reservoir was empty from looking at it. Didn't want to chance driving further without getting it checked again. Called RAC again & was on the phone to them for 25 mins as call handler couldn't locate petrol station I was at. I was called back by a supervisor who eventually located where I was & said I would be put as a priority & a recovery vehicle would be with me within 90 mins. Numerous text messages were sent telling me I would get an update in 30 mins. At 23.15 I rang & was told I would have a 4 - 5 hour wait !!! How is this acceptable treatment for a lady on her own ? Eventually I got a call from an independent recovery service at 12.15am to tell me somebody should be with me within an hour. I would like to add this man I spoke to was lovely, very sympathetic & apologetic for the long wait even though it wasn't his fault at all. After many many years of being an RAC member this has to be by far the very worst experience I have had with them & I can honestly say I will not be renewing my membership with them again.
