balance detect

Tata docomo company detect my balance 100 rs … Then I call to customer care and asked why did you detect my balance he said that you are using multiple surfing but I did not use multiple surfing. How ca n I use multiple surfing when speed of docomo is too weak even to open one page its take too much time then how can I open another window at the same time. Please solve my problem otherwise I will take seriously action against tata docomo company.
