virgin moble #MUST FALL

Sorry I can give this a negative star rating. Virgin Mobile stole 100MB and plus minus R121 from my account. Yesterday I loaded 50mb to check my emails. Even before I was able to check the mail, the data was gone, with in a minute. Phone Virgin and rapport it, something about their system down. Put another 50mb on, immediately data go and more than R20. Not even a minute. Phone them after my meeting. They will escalate it to technical. This morning I switch my data on, R50 gone. Phone virgin mobile, what is the old lame excuse, there are apps running in the back ground. Do virgin mobile think we are stupid? For more than 18months everything was working fine the apps was always running in the back ground. And then suddenly these apps start using extraordinary amounts of data at once. And in half a minute this apps take 50mb twice and more than R121. This is *****ing. I think virgin #MUST FALL....pathetic to say the lease....
