Terrible, unsatisfactory service

Zero rating will be more accurate. I placed an online order on 17 April. Telkom phoned me back and confirmed all my details. During the process I realized that the unit I ordered was not mobile and it was changed to a mobile unit, the new amount was confirmed and approved. I've waited a couple of days and received no phonecall for delivery. I phoned Telkom again. The lady that answered said my order was never processed and that she has sent it through for processing. Another couple of days went by and I phoned again. Then I was told again that they can't see that my order has been placed and promised to do so. The last called a couple of days later took my details and promised me that his manager will contact me to resolve this issue. Up until today 02 May, nothing has materialized. I challenged them to listen to the recordings that were made on 17 April, but it seems like Telkom is not interested to resolve this issue.
