MTN is so shady

I signed up for the Superflex unlimited plan online on the 7th, was given no option for a debit date. Once I ported my number over, I called customer service and advised that they did not have an option to amend it. How does an established company such MTN signoff on such a ludicrous assumption. The agents advised me to log a complaint and I've been waiting for a response since the 7th. I guess only way to get the date I want is to cancel the plan, then reapply on the day I want the debit order to go off. This means I will be charged for 15 days I essentially won't use. Are customers really expected to pay for MTN's oversight and lack of communication? Why don't you state this upfront in your marketing, why are you being so shady? The least you could do is equip your front line adequately, is that so much to ask? It's sad to see that hellopeter is the only way to get your attention.
