MTN made4me chowed my airtime and data.

I recharged with R40 airtime this morning and used it to purchase data. However, the data has not been loaded, and the airtime has disappeared.

I have already contacted your customer service twice, and on both occasions I was informed that they cannot see the recharge on their side and that nothing can be done. This is very concerning. Kindly assist by resolving this issue and restoring either my airtime or the data purchased.
