Pathetic service from Hollard

I have not been with Hollard long and have had the total displeasure of having to claim with them twice, their correspondence is terrible and never get back to you, you will always have to chase them up, the first time i claimed for a service and waited for them to cover it, sent all documentation and have to keep calling daily, my car ended up being overdue for the service, second time i decided to pay for the service cash and claim as this was an option, however it has now been two weeks, and havent have even a response to any off my emails.
