MTN Appalling Service

I bought a data bundle for R179 on 3 December 2022. It was for 15 Gigs valid for 30 days. On 6 December I checked my balance and it show I had 262 MB valid until 7 December - not possible also considering it was supposed to be valid for 30 days. After 2 days of much frustration, I managed to "speak" so someone on FB who finally said they had reloaded and refreshed my original data bundle and I was to take the sim out, leave it for 5 minutes, reinsert and check again. I got the same result so I went back to original person I had been in touch with on FB and since early yesterday morning have received absolutely no reply. Very frustrated - I desperately need this for work.
