poor customer service

I have been a customer of Telkom mobile for the past 7years and always supported Telkom even when my family and friends complained that the service was bad but I ignored peoples remarks and told them that the Telkom store at the Chatsworth Centre was super amazing and the staff was so knowledgeable about the products and was not interesting in making a quick sales but on Sunday the 09th August 2020 I was the worst service ever I wanted to upgrade my contract to DSL Unlimited home lite, so I the trainee at the store did the required protocol and told me to go the requested counter whilst the trainee was talking the agent 'name Sibonlo did not communicate with his colleague but just walk out the store so I was told to wait I waited for like +/- 20mins and this agent never came back and no one knew where he was with this pandemic no one wants to be waiting in one place too long I felt that the sale agent should have done the decent thing and excused himself but his attitude was like he is doing the people some kind of favour in being there and this lack of respect towards people will cost the branch a whole lot of loss in sales and I have chosen to cancel my existing contract because I feel this is no way you behave in any organisation we should be shown some respect and if you excused yourself that would have to been the decent thing to do
