MISSING DATA AND AIRTIME

On saturday the 8/815 at approximately 10:42am I loaded R90 airtime and them immediately converted it to the fortnight data bundle for R89 but that never reflected. I called MTN customer care 173 number several times and no one was assisting me! at 12pm the same day i loaded another R90 and changed it to data and that came through. So on the 13th i called in again and spoke to Lungile Vilakazi and she told me my data would get refunded and i am still waiting! i tried to call last night and it says my free calls are done for the month. THIS IS THEFT AND I WANT MY DATA BACK!!!
