Maruti Suzuki India — Dissatisfaction of ac work done in my car up 32-br-8700

Address:

Lucknow, Uttar Pradesh, 226010

On the suggestion/request of service manager of m/s one-up motors, gomti nagar, lucknow - 226010, i have allowed for full service of a/c of my above mentioned car, at end of last summer season. But for this service my car ac is not cooling properly. I have made so many complaints to m/s one-up motors verbally. They called my car for rectifying this problem many times, but my efforts remain unfulfilled. Fortunately winter season comes and the problem remain pending. Now once again summer season comes back and my problem once again arises.
Kindly do the needful action at earliest to save the reputation of maruti suzki ltd.
