Maruti Insurance — Re. Clearing black list at mumbai RTO

Good day sir
Please note, i mr. Leo P Dsouza owner of swift MH48S1160, has exchanged this vehicle for new purchase of s presso vxi, GA03Z6127 on 27 sept' 21. The above mentioned swift has a black listing at the RTO office in mumbai, reason being insurance cheque bounce 5 years back. Since then i hav paid 5 insurance premiums & taken one insurance claim last year, with out any problem, i have surrendered the swift vechile to maruti sai service mapusa goa.
From mid sept '21 i hav been communicating with maruti insurance mumbai to resolve the issue of letter submitted by the insurance company to RTO mumbai but to date no action seems to be insight.
Today the advicer from sai service mapusa has called me to inform that they have not received payment of ₹170000 from concerned party & transfer of sale of swift vehicle is held up.
Person concerned at sai insurance mumbai, is ms mitali & her senior ms rohini.
My humble request is that the concerned 'mauriti insurance, insurance company, maruti sai service. Take the matter up as urgent & serious and issue a letter to RTO Mumbai, asking them to remove the black listing so that the above vehicle can be cleared. i hav signed all required documents of sale & handed over the vehicle to sai service mapusa, having a letter issued by sai service mapusa, of no responsibility for the above said vehicle in case of accident or damage or theft.
I have been a dedicated customer of 5 maruti vechicles, since 1996, having faith & trust in the company & maruti insurance, hence i deserve to be treated accordingly
Thanks & kind rgds
