Hathway — Upload speed problem

I have taken new connection on 12 Jun 21 my account number [protected] before making payment, I have clearly told the requirements of 50mbps upload/download speed. Your reps suggest 3 months plan which is as per your requirement and you have to pay Rs 3009/- same have been paid but today after connection I can't do the stream, when I checked out the speed it's 50 mbps upload but download only 5 mbps. I asked the reps he said he will check out with service engeener, after half an hours received a call from your reps Mr Netaji said that you will get only this much speed only. Why your reps didn't tell me this before, he is the one who suggest after told him my requirement. Now it's is my humble request as a special case following may be considered:
a) My requirements at least minimum 15 mbps upload speed.
b) Download speed can be reduce to 45 mbps from 50 mbps.
c) If not feasible, request disconnect the internet connection and refund my amount.
Early action highly appreciated.
