Bidvest Insurance is the worst!!!!!

We took out a econo double cover on our Volvo. Our car went for a major service (which we were happy to pay). The service provider notified us that our fuel tank is leaking and the whole unit needed replacement at an additional cost of R7500. I have send in the quotation accompanied with all the details, asking for assistance. This was 11th January 2022. The email was sent to their Info and claims department as we were not sure how to go about and I was requesting information. The car was worked on in the mean time as my husbands work depends on it. On 13th January I resend the emails again, adding the complaints department also. I phoned the 14th January 2022 and was put on hold and used up a R35. 00 topup phone card. Nobody bothered to get into contact with us. I once again send an email with all the documentation as an attachment to the different departments, hoping to get some response. This time i also send the receipt /invoice of the payment we had made. Still there is no response. I phoned them once again and this time my phone number was taken with the confirmation that i will be phoned back. Up to date there is no communication from them. This is the an absolute disgrace as they are very quickly on taking our money every month, but when it comes to service..... There is nothing!
