Request for DATA Refund 1.5GB and 1GB

I have bought 1.5GB around 10:46 yesterday 21 Nov 2023 and another on 1GB around 12:56, as the previous got chowed and I don't know how.

I phoned their 135 line and got through to Philisiwe and she couldn't assist as my number is under contract. She directed me to the Techical Dept and I spoke to Chris and we checked what might be eating the data, there was nothing as I don't have any subscriptions and my app only update through WIFI, and also confirmed that my Data just dissappeared and MTN should refund me.He then advised that I speak to their consultant so that they can arrange refund. The 1st lady I spoke to by the name of Fezeka was irritated and told me that my DATA will be refunded within 24 hours and I will get the sms with the Ref No but that didn't happened. Until I phoned again inspire to another lady and she gave me Ref No. I am really not happy with what happened and the inconvenience that this has created as I use my data when there's loadshedding and Hotspot my laptop for work purposes and I only buy normally 1GB and that last me almost the whole month. MTN should refund me as I didn't use that data and spending R79 and R99 it is not a child's play for only 2 hours. My MTN number is ***
