Discovery Bank

I was paying my TFG account with a preloaded beneficiary from Discovery. The TFG are unable to trace the funds and said my bank has to correct this from there side. I submitted all the info to Discover Bank on the 30 of June. I have made countless call to them to follow up. They only call me back once with feedback after my 2nd complaint. Today I got to the point where I’ve said that if they don’t call me today that I will close my bank account and guess what... still no call from them. Discovery Bank has no interest in keeping me informed about where my money has gone. My account is in areas with the TFGroup, there are penalties and who knows what else that’s put me into bad light with them. Please can you assist me
