Holding my money???

Absolutely disgusted with the behavior of Nedbank!!!! Sent an e wallet which could not be withdrawn so sent the e wallet again knowing that the undrawn amount would be returned within 48 hours like so many times before. This happened several more times and now I am told that the few thousand rands I’ve sent can only be returned in 30 days!!! I have been on the phone and to the branch with no success from anyone on this matter!!! I did it outrageous that a bank has the audacity to keep my money from me for an entire month without my consent or approval and disgusting that no one can even help me when I have tried to resolve the problem. This is clearly a bank that doesn’t actually care about its account holders!!! As no one has so much as called me or provided any idea of a solution or why they have changed from 48 hours returning to 30 days. An international transfer could have been done 3 or 4 times in this time frame!!! I cannot even believe I hold a bank account with an institution that thinks this even remotely acceptable and I will be changing banks as soon as possible with this blatant disregard for me as a consumer.
