That will then go off as part of the next debit order. All of a sudden this stoped to work and she get's a message that she does not have any credit do so the transaction.</p> <p> </p> <p>I've phoned MTN numurous times. Everythime they say it is fix and that they will load it manullay for me. At the moment I'm out of the country. So my wife phoned to load data. She has my pin and ID details and MTN refuse to load data for her.</p> <p> </p> <p>Can useless MTN please assist and sort out your technical issues and answer me on 2 questions please:</p> <p>1. Why can;t she use the USSD *141*2# to reload data if she runs out of data.</p> <p>2. Why can't the Customer care assist her to load data, Everytime you keep on the call for 30 minutes.
