Uber India — driver asked for a different amount than the original

Address:	Gautam Buddh Nagar, Uttar Pradesh, 201301
Website:	Uber.com

This is so inconvenient and unprofessional! I had booked a cab from ndls to noida sec 125 on 22nd of sept, 18 for which my drive asked me to pay ₹290 which was the amount flashing on his phone! I gave him the amount that he asked for and then left... After sometime he calls me up and tells me that the amount was lesser than the original..₹438 and he asks me to pay the remaining ₹148 through paytm to ‭+[protected]‬ this number which is no even related to uber! I don’t know who is this lady who called me up and harassed me to pay ₹170 which is not even the remaining amount!!! And when asked, this lady has no recipt no details of the trip!! I don’t know who she is and how did she get my number!! I am ready to pay the remaining amount but i have no viable information about this number! I am being mistreated!! And this is not even my mistake!! What should i do?!
