Passing the bucket

I've purchased data via my banking application for MTN. I have contacted them after the data was not allocated to my number. After numerous calls and waiting what felt like forever I was told on one of my calls that the data will be allocated within 20 minutes. Grateful for a resolution, I resumed my day. When I finally got home and had the opportunity to check my balance nothing was allocated. Needless to say it has been 24 hours and nothing has changed. I have contacted my bank and they claim the issue is on MTN's side and on my final call to MTN they also ***ardly did the same as the bank. Neither accepting responsibility and neither willing to rectify the issue at hand.
