Pitstop — 3rs class poor service, do not recommend

I was having a pathetic experience with pitstop, these guys will fool customers who have no knowledge on cars, when i gave my car for service(coolant runaway issue), the pitstop mechanic charged me 8k for fixing the issue, after few days not even ran 100kms, the same issue re-occurred again, these guys took vehicle for inspection and quoted 16k for head gasket change, when i reported to them that why it was not fixed at the 1st attempt, guy called Ranjith and pasha from pitstop said that noone can see the burnt parts inside the engine, hence it was missed, when i said then its your mistake they said i need to pay the amount nobody will do it for free of cost, i also have the chat conversation with Pasha stated that no repairing cost will be added this time, but on call Ranjith asked me to pay for the repairing and labour again.I also assume without opening the engine how can they say the head gasket is burnt.Please choose a trusteed local mechanic or Authorized service center its our hard earned money.Ans guess wat when i observed carefully the fault was not headgasket, the coolant runaway was from coolant reservoir tank, which i replaced with new once at 2000rs only by my self.#pitstop please stop fooling people who have no idea about cars, and you guy Ranjith was very rude with me and dont know how to speak, train him to speak in polite way.
