Bad customer service

I have an insurance claim which can't be finalized because i bought q diningroom suite for R20000.00 and because the glass of my dining table that i dearly love, no one can install the glass. I called PG glass spoke to Anthony and said yes they can replace the glass but no one can install the glass. I had to email PG glass the pictures of my table. Last week Friday when i called to check on the progress of my claim. Was told to get aquote for the table so that they can't get an Installer. I told the consultant that the table and my server won't match. On Wednesday, i got a quote from UFO and the table costs R20250.00. When i told Maureen from the insurance department, she said they cant pay R20250.00 for a table as the price is more than the whole diningroom suite. Maureen said she was going to speak to her Manager to give advice. Maureen promised to call me between 12 pm and 13hrs. From 14hrs i called and was on hold for too long, then the call dropped. I managed to speak to Mpho on secure chat. The service is pathetic and now i spent Christmas without a table. I want my claim to be finalized on 31/01/21. Because of your poor customer service I'm not going to accept a mismatch in my diningroom. My friend told me Outsurance is the best and claims are finalized within 5 days. When i asked Maureen for their turnaround time to finalize a claim, i was told it varies from claim to claim. What type of business is Fnb insurance not knowing there should always be a turnaround time on any query or complaint or claim. No one bothered to call me today even though Mpho from secure chat escalated my query.
