Red Taxi — Driver charged extra amount in trichy

Dear Sir, Driver charged extra amount saying Red Taxi network server not working today. Due to that he mentioned malakal kondarpattai instead of ponmalaipatti. So he charged additional amount of Rs 50. Normally from ponmalaipatti to Srirangam us 248 Rs. The same driver charged additional Rs 50 when he picked me from Abhirami hotel trichy central bus stand to ponmalaipatti. Saying same reason. Driver mobile number is [protected]. He cheated me. Please avoid this kind of cheating person. I am not happy with red taxi. I even tried to complain to red taxi contact cell. But they are responding. Please help.
