Appalling customer service

i am having a terrible time getting hold of customer service to cap my line, been trying them for a week now and nothing. I am on hold sometimes for 15 minutes. this is ridiculously poor service. spoke to their helpdesk as I needed to find out about my power bank that has not been available for 10 minutes and the lady says she cannot help me with capping line and immediately transfers me to customer service where I again hold with no answer. I had to call another time to request feedback on my power bank and the man who said he will query it never came back to me. does Telkom want me to take a day off work to stand in their long queues to get some information on the services and products I need? I am appalled.
