Poor service from your service champion, *********** to to their job

Bought today data for myself R99 9G and bought for my partner same value on mtn app I have made two calls at customer service both service champion are not competent to assist to investigate my transactions I got my data but my partner number *** didn't get her data so both employees can't explain to me what happened to my airtime for both transactions and their system is not giving them my transaction history I'm starting to worry if I can now trust their apps and online purchases, worse of it both service champions just muted the calls so I can dropped the call and that is unprofessional from them to do such on clients and I need my calls to be listened and explained to me what is the issue of them not be able to assist me on call and request me to send an email
