EDGE and that's it ***

Good day,<br> <br> Connect remotely from current location for six years. Four years Vodacom and two years MTN. Devices Nokia Lumia 920, Nokia Lumia 520 and an Alcatel OneTouch issued by MTN Android device. Since Friday 25 September 2015 all I get is EDGE connectivity with 3G every so often. I am unable to do my job because the damn connection is just too slow. <br> <br> Called the call center on all three phones in fact all my phones it says that my accounts are in arrears with different service providers but that's another story.... and all 3 MTN phones only report EDGE connectivity.<br> <br> Called the prepaid call center and they were very rude and did not even give me a chance to explain what the problem is. I understand that the main phone is in the name of my company I work for but this is a technical query. Can your agents not use their brains and understand that there is a problem and it needs to be addressed.<br> <br> All I want is someone to log a call and investigate why there are no more connectivity above 3G. No HSDPA, NO LTE.. only EDGE .. *** have you guys done.<br> <br> Imraan Grace
