Pathetic service

All I wanted to do was to up upgrade my cell phone contract. went to the Telkom mobile store in blue route mall. Spoke to the consultant Shanae and on the last step, I was told something had to be unblocked from my previous upgrade 2 years ago and it would take up to 72 hours. A week later, 2 telephone calls and 3 trips to the shop and after i was advised by other staff members at the shop that I could come in to collect it still has not been resolved. Was so upset I cancelled the upgrade, Utterly disappointed in this poor customer service as I have had no issues with Telkom as a provider.
