MTN app and customer care

I bought 3 times airtime on the MTN app but I never received my airtime at all. I bought R100 airtime on the MTN app on 24 March 20 only to receive an email by MTN and sms saying that R100 has been taken from my account from MTN Service provider. I called customer care spoke to Mpho Legoabe who said we changed to a new system. Please can you email me the proof of payment. Which I did and she immediately called me back. Then her excuse was madam you must wait 24 hours for airtime to be activated email me again tomorrow if not received. I asked her don't I require a reference number No. I emailed Mpho next day to tell her no airtime loaded. Never called me back Then on 25 March I call them again only to get slack from two of the customer service members put on hold then line went dead. I then decided send customer care an email about it emailing them the receipt of payment myMTNapp sends automatically to you once payment is taken.. I get a Reference no: *** with auto reply saying they only respond within 8 business hours. The next day 26 March Matilda Dlamini emails me back asking me below details for security and verification details. I answer her back with the details. No response from MTN at all on 26 March. Then next day on 27 March I receive an email from Kholofelo Sethibela saying apologize for the delayed response. Please provide us with a bank statement reflecting the transaction in order to assist. I was shocked!! We are in a Shut Down! So I emailed the person back said scroll down you will see payment has been taken off and attached is a screenshot via sms from my bank showing that R100 airtime was taken from MTN Service provider. I then said could you please either put the R100 airtime into my airtime or refund me back the R100. To this very day no one from MTN has responded to me at all and now due to MTN I'm out of bundles with airtime and data cause of their BAD SERVICE and not getting back to me at all! I was told by one of them at customer service that they would be working from home due to Shut Down. So if you are working from home do you not assist people we have technology etc to help and assist one. MTN your stores at the malls and customer service has become so BAD and the attitude of your staff in assisting with anything has fallen short. My advice train your staff better to handle clients with a friendly, helpful attitude and not a I don't care attitude. All I kindly ask of MTN is for my R100 airtime and to advice why when I buy airtime on the myMTNapp I never get my airtime at all.
