ATM Dispute

I withdrew an ewallet worth R2 100 on 29 July 2018, money didnt come out I immediately called ***** line and was told its because they are offline. Money will reflect back the following day. On 30 July 2018 I checked balance there was nothing, I then called FNB and i was told according to their system money did come out so I have to put in an ATM dispute which will take 7-14 days. After 14 days which was on 16 August 2018 I called again and was told they haven't received a response from atm department and my issue will be escalated to team leader, 16 days down the line my issue has not been attended to, I was made to wait on line while they try to see who is the team leader that my issue has been escalated to until my airtime ran out. I am sitting with a negative balance whilst FNB is keeping my money and taking me from pillar to post. I want my money this has gone for far too long, FNB is so unprofessional, will never ever join this bank. I'm sitting here with more than 5 reference numbers for every call I made but my money is still sitting somewhere.
