Havells India — Charges undue amount from the customers for services.

As we are regular and old customer of Lloyd AC / Havells AC . But, sorry to say that we are not at all satisfied with Havells service centres and customer support.
As Gas filling charges of carrier and other reputed AC of R 410 is 2400 + GST. This includes service charges and rectification of any leakage.
But, sorry to say your service centres are taking undue advantages of their clients. Initially They raised bill of 4050 + GST for Gas filling. But when we said that other reputed brands are taking 2400 + GST.
Than they made another bill for rupees 3500 + GST.
