Overcharged and bad after- sales service.

According to our insurance company we were “grossly overcharged”. We were charged R14,690 but Accor to the insurance company we should have been charged about R9500 The insurance company requested an itemized invoice so that they could see if there were additional parts used in the installation of the new geyser. Despite numerous requests, the company have not provided this information. The only reason I have given 1 star rating is because a minus star isn’t available. Would never use this company again.
