ATM Sendi-Mali transaction Query

On the 24th of November I sent a sendi-Mali to myself using my other 071 cellphone number, when I got to the ATM money never came out when I punched in the voucher number. I then re-entered the number to my surprise the slip came out saying the voucher has been used though I didn't get money from the ATM.

I immediately called Nedbank call centre on *** and a query was logged, I was told to do a follow up in 2 days if the money was not deposited to my account, well a week passed with no money back to my account. Thursday the 1st of December I called in only to be told that the query was cancelled because the person captured my details captured wrong account number and a new query was done. I then followed up a week after only to be told again that my query was cancelled transaction not found blah blah blah. Today is the 6th of December I went to Westgate branch to do the same query but I was told to call the call centre again and do another query. Am I going to get my R250 Nedbank though? I'm worried about this kind of service, say for example this was R5000/R3000 sent to someone for groceries same thing happened and they from Rural areas how will they cope with this sending from pillar to post if this happened to a simple R250 that I don't know what happened in that Meadowpoint ATM.
