MTN - WORST CELLPHONE PROVIDER EVER

Purchased 10GB data yesterday afternoon. By this morning the data was all gone. I checked my MTN app and it said I had only used 2GB over the last 7 days. Called MTN Customer Care to find out what the data had been used on. They couldn't tell me. They logged a ticket and within 2 minutes they closed the ticket again. No explanation. No feedback. PATHETIC SERVICE!!!
