Glasfit 5x overpriced

I registered an insurance claim for a broken window shortly before Christmas 2023. My insurer arranged for Glasfit Centurion to do the repairs and advised that they will only be able to assist on the 27th Dec, which I understood as it was Christmas. The 27th came and gone. When I still had not heard from them today (28th), I followed up with my insurer who then got hold of them after struggling at first as there was no response on their phone line. I was then given a quote for the glass only (as my insurer covers the callout and labour). The quote for the glass was 5 times more expensive than the quote from my local hardware store (R2100 vs R415. Same size, same thickness of glass. I can understand if it is slightly more expensive, but 5 times!!?? When I queried this with the manager (Vernon), I was given some lame excuse that he has travel cost and call out fees to cover. When I reminded him that my insurer pays for that, he tried another angle saying that he has greater overheads compared to my local store etc etc. Some operation that, to have overheads that warrents prices to be 5 times that of my local store! I tried calling the Regional Manager but after 7 unanswered calls I gave up. I ended up cancelling my insurance claim and had my local store do the repairs instead. Disgusted.
