Bad customer service

The customer service at Telkom mall of Africa is F***ing poor, the queues are always long. I opened a new data contract on Monday 29/01/18, they told me it would take 72 hours for it to be processed, they notified me on Friday 2/2/18 that its approved, unfortunately I couldn't go that day, they called me on Monday 5/02/18 to come and collect it and I told them I would come during my lunch time, when I got to the store they told me that my contract has been cancelled and when you ask them why, nobody could give me an answer(not forgetting that I waited 30 minutes before being assisted), when you ask for the manager, he can’t be found. They wanted me to start the process from start meaning I had to wait another 72 hours, Bull****, you have the worst customer service and your employees don’t even care. The lady who was processing my contract is Dinah
