Poor handling of my claim

My car was hit by another motorist in January. I submitted my claims with Innovation Group on the 5th of January. I had to call them to make sure that they register the claim (registration date was 8th January). After registration they took 12 days (20th January) to authorise my claim. Because I had 2 claims for my car they forgot to authorise the other claim till I called them on the 10th February.<br> <br> Till today I have not received any apology for this however they claim that its not their fault it is the Repairers fault. The Repairer proved to me that its not their fault at all and Innovation group has not come yet to prove to me. I have incurred unnecessary costs due to this delay.
