Data sim card not working for 3 weeks

We are absolutely fed up. For three weeks now, we've been passed from person to person all of whom just keep repeating the same nonsense to us about APN settings and reprovisioning the SIM card. The APN settings on the device worked fine with the previous sim card which was also from Axxess.<br> <br> We have asked to be supp**** with a new sim card or even just the transfer of the data that has been paid for to the other Axxess sim card that we have but it seems they are unwilling to assist. Tired of paying for a service that doesn't work!
