Been trying to fix my phone for a month

Good day,<br> <br> I've been trying to get my blackberry bold 9790 fixed for a month now.<br> <br> Before I explain the problem, I would like to mention that everything is working fine on my blackberry curve 9320. So it's not the simcard or battery that's causing this.<br> <br> On my Bold 9790, in the right corner it says: EDGE, in the service status it says that blackberry internet service is not connected, while it's working fine in the other phone.<br> When I try to access Blackberry ID it says: \Unable to update Blackberry ID account information while offline"<br> The blackberry world icon has disappeared. When I try to activate my email it says: \""Activation failed. An error was encountered when sending the activation transmission.\"" <br> Whatsapp is also not working.<br> <br> The man I spoke to at vodaworld last week monday"
