Poor service MTN

I bought 30 days data 10GB anytime and 5GB nighttime in the middle of Jan. This was to expire on 20 Feb 2021. A special on the back to school option. On 01 Feb my anytime data had almost run out and when i checked i saw that the data had been loaded as the opposite. I called got ref # *** and have sent several emails since then to date no response. Inconvenience causef to me as i have had to incur costs to buy data since then. Very disappointed in the poor service.
