I had purchased a BSNL 3G dongle back in January, and had opted for the Rs. 4200 UL Plan - Postpaid. Of course, earlier this month they withdrew the UL plans. I was under the impression that existing customers won't be affected. However, it seems that I was mistaken. I just received a bill of Rs. 15,000 for data usage beyond 15GB. BSNL did provide a rebate of Rs. 6,000; however, even then the bill is quite hefty. I didn't receive any notification regarding my plan being changed. This saga reeks of unfairness. What is TRAI's stance on something like these? Does BSNL have the right to switch my plan w/o notifying me in advance? What are my options at this moment? Guys, please help.
