Honda Cars India Ltd. — motor insurance claim

Address:

Kollam, Kerala, 691004

My car honda city 2016 model met with an accident on august 13th at kollam district in kerala. I take my vehicle to 'muthoot honda' kollam district showroom service centre. They took 5 days to get it done. Very poor service. My insurance is full on united india insurance. The invoice bill i got it on 19th august doesn't have gst number. It only has old tax no (Vat), kalyan cess and swachh bharat cess. Central govt has already put gst into effect from july 1st onwards and yet muthoot honda kollam does't change billing system into gst. So after 2 weeks united india insurance officer called me and said the invoice bill honda given doesn't have gst number. Total invoice amount was 12000. And tax amount was 1600 approximately. Now they could only refund 10500. I would be get a loss of 2000 rs. So insurance company could only refund the amount excempting tax. When i called muthoot honda showroom kollam they said they cant do anything and they didn't took my call after this. So i decide to go to customer court to register a complaint against muthoot honda kollam. Kindly varify this issue. My vehicle no is kl 02 aw 7476, email - [protected]@gmail.com
