Mtn online sales people will lie to you just to push the sales

MTN sales people are full of lies.last month I subscribed for a month to month uncapped wifi and I told the lady I want my debit order to be on the 21st she said I must wait for the first debit order on the 15th this month and then I can change to the 21st after. She was a Zulu lady I forgot her name you could see she was happy for the sale that is even lying about me being able to change my date. Today I'm phoning them the lady by the name of Michelle she is giving me I don't care type of attitude. This is the worst service by mtn. As much as they want sales they must give honest and truthfully information. I'm honestly ****ed and even thinking of canceling this nonsense.
