Absolute nightmare Volvo assistance experience

[tspdavish]

Advice would be appreciated.

Car is: XC90 2016 plate, Volvo dealership service for life, last service in April. Has Sytner Selekt warranty which has paid out for a new ERAD earlier this year.

Situtation: 17th December, cold weather. Compressor for suspension went caput. Called volvo assistance who towed it away later that evening, delivering it to my local dealership a couple of days later. The day after it was towed they put me in a taxi to my local enterprise hire centre where I was given a hire car.

I signed a contract for insurance etc. for the hire and was charged a nominal £1 on my Amex and was told, verbatim, I would not be charged any more and Volvo were covering this (by Enterprise).

I drive around quite happily and confirm with the dealership they have my car. Due to sickness there is a big delay in getting it sorted and won't be done until 6th Jan.

Meanwhile 2 days ago, so nearly 2 weeks after the Volvo was picked up, I have been charged £600 by enterprise on my Amex. They have said Volvo only paid for 3 days, they couldn't contact Volvo (or me despite them having emailed me and having my phone number) so had no choice. They tell me to call Volvo Assistance. Volvo now say they can't extend the hire until the dealership tell them a date for repair. The dealership no matter how many times I call, are not contacting Volvo assistance. Furthermore they now say it might not be covered as the car is out of manufacture warranty.

I am gobsmacked at no point in these 2 weeks have I received a phone call from anybody, or that I would be on the hook for the hire car.

Any tips or previous experience of this?

Thank you in advance.
