Bad insurance business

I have a Value added policy together with my main policy with Dialdirect which cover scratches & dents as well as tyre & rim for almost a year and never claimed. On 30 September 2018 I wanted to claim for a damaged tyre but was told that the claims dept don't operate on weekends(contrary to the 8am-1pm on Saturdays stated on the comms i was sent). The following Monday I called in to log a claim and was asked to sent through docs and pics which i did and got told that I would have feedback within 48 hours. I was never contacted and everytime I phoned, I was told they'll get back to me. It's been more than seven days later of me phoning and got told today that they will be authorising the claim. I had to make use of my vehicle during this period and had to purchase a new tyre myself because of the uncer*****y and lack of feedback, and are now told that the claim will be rejected. Ridiculous service and not a insurance company i want to do business anymore....cancelling policies straight away.
