Appaled furious by escalted bill with MTN

I have always had a data contracts and prepaid with MTN. 5 june or July i signed up for another contract for more data. First month or two i paid the normal amount which is R295 for both contracts.

Suddenly this month my 1 contract of R95 has escalated to R412 .

I dont understand how this happened and the store says at the time of my new contract my limit was not set back to 0 by my consultant.

Now what must i do MTN this month i am suppose to pay R612 altogether.

1) it is not my fault i know nothing about setting limits i have always been just data and prepaid with MTN and that is what i wanted this time as well.

So how did this now change, but the first month or 2 i was paying normal and my phone was telling me when i run out of airtime.

1.I am furious, because then it means the consultant did not do his job properly. Or something went wrong with mnt systems.

2.And MTN the sad thing is that i am not working and single parent hence i took the R200 data promotion you had. So the sad things is where am i going to get the money to pay your bill of so much money????

So you are taking me to credit bureau for the first time in my life just because you guys did not do good customer service?

I am appalled by your sale people telling me i just need to pay it. There is nothing you can do.

Please sort this out. I do not have money for there extra cost other than the R295 i am to pay altogether every month.
