No Feedback/Response to my query

To whom it may concern,<br> <br> Last week Tuesday(02/06/2015) I logged a call on the self help page on Virgin Mobile regarding my cell phone number up until today, I still haven't received any response regarding it, except for the mail that I got to confirm that Virgin Mobile had received my query. The issue is that I am struggling to receive or make phone calls. I am not sure what might be the problem because when I put in a different sim card from another service provider I am able to make calls. This problem started on Tuesday until Thursday, from Friday I was able to make and receive calls until Monday, and started again yesterday. And the other thing is that when I check my airtime balance on the Virgin Mobile site, it shows R2.91, from R121 to R2.91...that doesn't make sense because when I check the times I made the calls it shows the days that I couldn't make calls and the funny thing is that the calls were made to my cell phone number and it shows that I am making calls every 5min.<br> <br> Your assistance in this matter will be highly appreciated.
