Telecom Namibia Worst Service

There is literally NO customer service at Telecom Namibia. I have been struggling for the past 3 days to sort out my account with Telecom and TN Mobile. I have contacted a call centre agent, a sales agent, the supervisor, the manager and still no one can provide me with clear feedback. A issue that could've been resolved within a day - is still not resolved. The worst is the fact that the supervisor and manager say they will phone you in the afternoon to provide feedback. Obviously no one phones to provide feedback. The next morning at 11 o'clock I need to make a call and follow-up with them - is this how customers are treated? This has been happening for the past 3 days! The management team don't even know what products they offer and the prices of the wifi packages. How is this possible? The customer service is unsatisfactory and I would not recommend Telecom Namibia to anyone.
