Terrible service from Technical team

The service I have been receiving from your Vanderbijlpark Branch in the last month is appalling. Technical team set up appointment for a system upgrade that has already been paid for and yeah you guessed right, they NEVER pitched. After numerous phone calls and being told they will still come through, the technician did not even have the decency to let me know they will not make it. I had to follow up numerous times. The worst service I have received. We set up appointments for a reason, if one can't make it, the decent thing to do is to inform your clients. We are not sitting at home the whole day waiting on your team to rock up whenever they feel is appropriate. The worst thing is this is the second appointment and the same thing happened (appointment was set up by your technical team).
