Virseker - Auto & Gen want to s**** my vehicle!!

I lodged a claim on 16th February after another driver reversed into my 2003 Toyota Tazz. Virseker asked me to send photographs of the damage to their assessors. On 29th February, the called me to tell me that they want to write my vehicle off! The vehicle is mechanically perfect so I took it to a local RMI approved panel beater who assessed the damage at half the amount of the "digital assessment". I was called by a lady called Caryn from Auto & Gen to tell me I had 3 options. 1, to s**** the vehicle, or 2, to go for a "Buy Back" option or 3, to send them my quote from my panel beater so that they could ask their assessor to re-assess, which will apparently take much longer to settle the claim. I am 68 years old, I live on a SASSA pension and don't know the term "Buy Back", so asked her to email me everything in writing so that I could make an informed decision. She assured me that she would do so the next day. Friday 1st March. Needless to say, I have heard nothing. It also seems very strange that I have an excess of R2700 to pay. Other companies waive the excess for persons over 65. Apparently Virseker can do that too, but load your premium in order to do so. I have been with Virseker for at least 5 years. Why didnt they tell me that my vehicle is not worth insuring?
