Muddle and Fuddle - Poor service and no feedback

Submitted a claim for a windscreen which was approved & a few days later received call & 3 sms from 24 Fix (Outsource company) confirming date & time of repair by tech. I confirmed in order & no one arrived, followed up & was referred to another company 24 Fix had sub-contracted who said they were still waiting for windscreen. That was 19th Mar, last week I went onto M&F website & provided feedback pertaining to my complaint, when I did not get a response I logged another complaint on their website, still no response. Tried phoning M&F today to log a complaint & was referred all over the place eventualy leaving a message with Nichole (helpfull) who said she would pass on my complaint to Claims dept, still waiting.<br> Also requested a review of my one cars premium 6 Mar via OMAdmin@.. as I believe I am being over charged & I was asked to obtain MM code for vehicle (whats that?) eventualy their consultant said she would obtain MM code & get back to me, despite e-mail follow up on 16 Mar, still no reply but I did receive an endor*****t increasing the premium on my other car ?? I'm a low risk client for 20 years with full product spec & this is how you treat me - shame on you M&F!
