Baddest Service ever *********** staff - UNISA DATA

I have been sending MTN communication since 23 May 2020 for UNISA data being that needs to be provided to Students. i even bought a new sim card for that matter, no one is willing to assist me, the matter has been escalated to their other department in which they requested me to give them the sim number at the back of the card but still awaiting the data, when i call their 135 number you get *********** staff that doesn't know what to do, i don't understand as i have to research and use that data for my exams .. i have already written my other exams without the data i need that data as it is due to me.. i need urgent response from MTN as i have to write other exams soon. and cannot afford to buy data.

Please assist urgently

the numbers in questions *** 1st number which still doesn't have data *** second number i bought still nothing is happening.
