Called R.A.C today and explained that my car was in a multi-story car park. Pointed out to the operator that there was no mobile coverage within the car park so I would not be able to take any calls if l was with my vehicle. I gave the name of the carpark. It's location but not the postcode. Which floor l was on and the aisle. I was told ut would be a 90 minute wait. After waiting 2 hours l called back to be informed my call-out had been cancelled due to the mechanic not getting a reply from me when he tried calling my mobile!? Waited a further hour for a mechanic to arrive who then informed me he had been to several other car-parks first because he had not been given the location information l had provided. I might have still been there waiting had l not called back. Very poor comunication.
