Car breakdown HELP
 

Hello
Our car has broken down.Although we have breakdown insurance they are being less than helpful in finding garages and have already changed the dates twice,forcing us to move our crossings and extend our stay.We've rung round a few garages and no one seems to be able to do anything for us for up to 3 weeks,which would mean rebooking the crossing again.
I'm asking if anyone knows or can recommend a towing company that can take our car (Hyundai Santa Fe) and caravan (7 metres long,1500 kgs) and 2 passengers to Santander for the morning of 26th March ?
We are currently in Los LLanos between Denia and Gandia.
Any help would be much appreciated

Richard
