Not impressed !

I joined the RAC because i travel often to shows with a trailer as a hobby. I had a blow out so changed the wheel with the spare and took it steady the rest of the way home stopping regular intervals to check my tyres etc. It was on the M4 j36 services that i noticed a tyre starting to peal it's tread so i decided not to go back on the motorway but to call assistance. The RAC refused to come out as i had no spare, i was off the highway, my car was fine and i had an illegle tyre but would do me a private recovery for £256. With no option i paid the money and then described my Trailer length, load weight, vehicle etc. The contractor who turned up said he had very little info and did'nt even know i had a trailer. He could take my trailer home so loaded it up and took off. Three junctions later he pulled in and said he could'nt take it any further due to the length of the trailer putting the weight too far back. Fair enough. the RAC controller then rang me again explaining that i needed a bigger vehicle to recover me and would refund the mileage cost but not the call out and i would be passed to commercial recovery. They quoted between £550-£750 to take me 70 miles home which i did'nt accept as i got a private firm to do it for £300.
The RAC still took the £256 i originally paid and i've sent a email on 6th may explaining and someone is supposed to ring me back within 5 days...i'm still waiting!. I spoke with someone who tells me that customer care is only open mon-fri 8-5, with work this is all outside of my hrs and i have no land line at work.
I feel pretty let down as a member and i'm not too sure if i will be renewing my membership at this rate.
