Complaint regarding servicing TVS Jupiter

service center. Value: 50000

I bought TVS Jupiter in 2020-21. And there was the problem of Jupiter not starting. Then I took my vehicle to my nearest Meenakshi TV service center. They told me that there is some problem with the scooty and gave me an estimate of around 8000. I said ok and they fixed my TV Jupiter and I paid my charges. .But still my tvs jupiter is not working properly. Again my scooty showed some problem and again I reached the service center. the again they are saying that,  you have to spent more than 8000 for repairing.So this absolutely fraud to the consumer by tvs company and service centre
