Poor Claims Procedure

Extremely poor service with regards to a claim I have submitted for a TV. After numerous phone calls to the claims department I have been told that my claim has not been authorised. I have sat without my TV for close on 2 weeks. Each time a call is made to the department I am advised that the SMS voucher will be sent within an hour........alas after an entire day of waiting no such communication happens. When a follow up call is made by myself I am told in an extremely rude manner that the wrong information has been filled out to Claims Card, which has been filled out by the claims department themselves.
