Virgin Mobile ****

I have a Samsung s3 which I upgraded in 2013. Prior to this my phone was an N8. Virgin mobile did not change that info. However it now reflects a buy out for a Lumia 520. If my phone is up for an upgrade only this year how can it reflect a lumia 520 n not a S3. This info was given to me guys virgin mobile consultant in gateway. I was asked to contact their customer care to rectify this. Wen I did they tell me a lumia 520 doesn't reflect and put me through to their upgrades which showed a lumia 520 and not a s3. How is this possible when one system is being used. This person said he will talk to IT dept and call me back. Its gone 4 days n no one called. When I called today 14/03/15 they cannot help n asked me to call on Monday. Virgin mobile has *********** people working for them an a useless system. I have been paying my account diligently and this is the nonsense I have to put up with. In 2014 customer called me over 20 times telling me I qualify for an upgrade. I kept on telling them I still have a contract which will only expire 2015. They would apologize and say they will get accounts dept to rectify the system. Please help..,,,,,,<br>
