Hathway — Regarding usage of my Account

Address:

Mumbai City, Maharashtra

I m a resident of Mumbai.I use hathway wifi with the d-link router. My hathway wifi account no. is 1063813 it is registered on the name of Ria Marwaha. My wifi plan consist of 10 GB downloading with 50 Mbps speed and further as i cross my FUP limit my speed gets downgraded to the speed of 512 kbps. I face problem regarding my usage every time due to which my speed gets downgraded and i have faced this problem many a times. This month that is from the 1st May 2015 to 9th May 2015 my account shows a usage of 5GB which i havent used and after the use of more 5GB my speed will be downgraded. I had even changed my password so that if by chance some one is using my wifi connection will automatically get disconnected but i still faced the same problem this month. If i had to use my wifi speed only for 10 or 15 days of a month i would have better have a normal LAN connection which would have cost me less or i would have selected another plan. I have complaint many a times regarding it still i face the same problem. I have even mailed the billingdesk regarding it but still no reply. As for now my speed is again downgraded when i even have not used my 10GB od downloaing or surfing and surfing or just using whatsapp does not take soo much from my account. I request you to please help me regarding this since i have payed my entire year amount and my plan expires in December. I have really done a great mistake trusting hathway
