Currently i am using reliance internet with wipod device. now reliance is upgrading to 4g, for that i am getting calls to upgrade my device to 4g device since my current wi pod device will not work with 4g. now they are telling me that i should buy the device.

first thing i have not requested to upgrade to 4g, then why should i have to pay for the device.in case comp is upgrading they should give a device for free (they can exchange the current device).
now from last 3-4 days internet is not working on wipod (since postpaid connection i have to pay the bill irrespective o[censored]sage).
not able to connect to customer care.
