Modi Hyundai — Worst Servicing of Car

I am owner of i20 elite
I had visited modi hyundai kalyan workshop near saroli bhiwandi.
I had a complaint of ac not working for this i have visited the workshop of which after inspection i got a estimation of around 90 Thousand Rs.
and was suggested to claim through insuarance but due to time required for claim process i got it done by direct payment system.

I got my car serviced forst for that i paid approx 25 thousand
And gave it again after 2 Days for ac repair . For which i again paid 22 thousand app.
And then after this new noise started comin from backside for which i was suggested to replace rear shock absorbers. And paid more 5500 for same .
From the day i got my car serviced i am telling my service advisor mr rohit patil that ac work which is done is not done proper because ac power cut downs automatically for which i got reply this is normal and it happens like this only.
Already i had done my car Ac service of Level 4 From modi Hundai thane 1 month earlier for 20-25 thousand .
And now ac suction pipe and radiator work is done after which i am getting this problem.

Please solve my issue
After paying such amount from authorised dealers we expect the good quality work and we get frauded by such type of dealers.
Please look into which type of people u are give dealership.

Hope my consern will be solved.

Thank you
