Bad Customer Service

Telkom advises me via sms that I am due for an Upgrade. For over a month now I have been battling to actually Upgrade. 24.05.15 Telkom Greenstone advised I had to come back within 9 days. I did, Filled in the application form and left it with the guy at the Centre with my ID, and relevant documentation which he requested. He kept a Galaxy Note 4 for me. Came back in 9 days, I was still unable to recieve the Upgrade. On their system says 0 Months, 0 days but still cannot release Upgrade. Telkom Call Centre was contacted and they said only in the 22nd Month can I upgrade, Which means in June 2015. 1st June 2015, I spoke to Jaydine Orlam that was there at the Greenstone branch. My Application suddenly was lost with all of my private documentation and no stock of the phone either. Jaydine Orlam was kind enough to get back to me on 03 June 2015 saying that I would have to fill in another application form and send back to her via Email. Which was sent with a certified copy of my ID. 05.06.15, I cannot get hold of the Greenstone Telkom branch on: ***, repeatedly trying to contact them for weeks, the phone is NEVER answered nor via email. Please advise at your soonest!
