How to deal with no responsive Hero vida vx2 service centers - it's the worst service/customer service ever even for first time service

I bought a Hero vida vx2 plus scooter, 6 months ago as a utility vehicle for local chores, and I was happy about it..

No so anymore..

I went on a trip for 10 days in Manali, then came back and the bike wasn't starting... I sent it to a local service center in faridabad...

By getting it picked up..

Now, it's been 10 days since I submitted it and the local service center is just unable to fix it.

I went there after 4 days after following up and getting no response.

Only To find out that they were unable to fix it and had to call chief Vida scooter engineer who was also not able to fix it. Then they told me it had wiring issues.

And will keep me updated on progress after complaining abt no response.

Now it's the same, i am away busy with work and these mfkrs are again not responding.

How to deal??
