This kind of service is unacceptable

The poor service we are receiving at Westgate mall is indescribable,i have been standing in a queue of less than 10 peopl for more than 2 hours just to do a sim swop, i fail to understand why telkom does not have a self service for sim swop,or telephonically ...I am really angry ..This is not on,they do not even have chairs to sit while in queue..how is it that they have 5 assistants who cannot assist less than 10 peopl in two hours
