I have been issued with a charge of £80 by CP Plus for overstaying my welcome at Forton services on the M6 (3 hous 8 mins).

In fact, we had broken down (or at least the vehicle was undriveable) due to a burst heater pipe, resulting in a total loss of coolant. When the warning message was displayed we were only a couple of miles from the services, so I took the risk of continuing to this safe haven rather than risk my family's safety on the motorway hard shoulder.

We parked in the lorry section which had plenty of space throughout the period in which we were stranded. The AA took over 2 hours to respond, but the repairman was able to provide a temporary fix so we could complete our journey to Scotland. Looking at other cases on your website, do you think I should offer a small fee in compensation, or do you, like me think this is totally unjustified? I intend to send a copy of the AA receipt and a letter explaining the situation and no money.
