Telkom needs training on how to ensure customer satisfaction

They are the worst service provider I ever dealt with. I spent so many hours on the phone with them trying to track my upgrade phone. Did my upgrade on the 29/11/2024 and was told on the 30/12/2024 that the information when my upgrade was done was entered incorrectly hence that is the reason i didnt receive the phone and it was a black friday special and the issue cant be corrected on the system as the deal expired. The service from managers right down to the sale agents and customer service sucks. Its so pathetic that all of them need to go for training and make sure they understand that their job is to ensure that they give the customer the best service and the customer is satisfied. I have been a loyal customer for over 10 years and its very sad how they disappoint their customers.
