MTN you are a disappointment!

In Dec I was cut off on the 24th after I had paid my account on the 22nd. I have been paying on the 24th - 26th every single month. Suddenly in December my account changed from the 21st to the 16th - I DID NOT ask for this to be the case, and I cannot pay my account earlier than the dates I have always paid as pay day is on the 25th.

Then about 2 days ago I received an sms to say that I owe R400-and something on my account and will be cut off. This is NOT even the amount that I normally pay. I have NO idea what is going on with MTN and why now all of a sudden my payment dates are a problem when they have been the same for the last however many years!!!

Today I was informed that this might relate to an unpaid account from 2015 - you have GOT to be joking me!! Who is having the laugh here right?!!! So if this is indeed the case it has taken FOUR years to inform me of this? Really????

Come now - this is ridiculous. I was given the "managers" email address which is incorrect and his "cell number" which goes unanswered.
