6 weeks still no upgrade

I have waited 6 weeks for my upgrade which was due 2 mon the ago. I have never been treated with such disrespect and ignorance before as I have with the agent who is dealing with me or better said is not dealing with me. He has a total disregard for me and has not once contacted me to tell me what is happening with my upgrade. He consistently blames other things and other services as well as blaming me and mentioning incidents which never even occurred. I have never been so angry and disappointed. I used to love Telkom and now I have nothing but disregard for them.
