Utter incompetence from Viacom support!!!

I called yesterday afternoon round 1400 to report a fault on a data contract, very slow download speed, and no upload speed, Ref 005302dd48a. Was told by consultant to wait an hour and reboot router, I did this. Now my Unrestricted APN no longer works, ie I cant port forward. so I call approximately 10 further times to get assistance, speak to Xolani Kunene who indicates that my Unrestricted APN is deleted, but assures me this will be rectified, Well, this has not been rectified! Ref ***, *** My Facebook messages also render ZERO support. What baffles me the most, the clowns in the support department have NO idea what an unrestricted APN is, however they have access to delete it, however cannot reinstate it, I AM FUMING MAD!!! Wasted my months airtime allocation on these clowns.
