MTN *****ing my data

I bought a 1GIG weekly bundle on 08/04/2018 @ 08:55

I did not do any downloads or streaming on the internet just searched a few sites and @ 10:40 the bundle was depleted.

I called MTN and they could not tell me were the data went exactly said I must call them on the 13th for a report.

The Customer service of MTN is useless. I want a full report of were the data went or my money back.
