MTN - you just ****med me

I am on contract with MTN. I was not aware that contract users cannot buy the social bundles, which a did, a 5gig YouTube bundle to be specific along with a 500mg, 30 day data bundle.

After a short while my 500mg data was depleted but the 5gig YouTube bundle remained untouched. After speaking to MTN twice, they very nonchalantly declared that contract users cannot use social bundles and they cannot refund my purchase. And on top of that, I need to phone MTN again on the 5th of January to hear the outcome of this saga, no one is willing to give me an answer at this moment. Meanwhile, I have no mobile data.

Why isnt there a prompt on the MTN app that makes it clear to loyal contract customers that they cannot use a service they are about to pay for? If I cannot use it, I should not be able to buy it. I cannot use the bundle I paid for but MTN is happily taking my money and refusing to refund. MTN is ******** customers this way, this needs to change.
