Disappointed Client

I went to African bank Sancardia to apply for loan it was on the 13th of December 2023 and it was approved the following day but now until today the 19th of December I can't access the money it was released into the African bank account that was opened on the same day of application, I tried to download the app and I couldn't ,then I went to the bank they tried but did not succeed and they send the email to head office and told me the head office will contact me within 72 hours as they have logged a complain. The following day I phone customer care explained the problem but It was not helpful, the lady I was talking to said I should try to download the app again,I tried and fail,I went back to the bank again, they told me my account is on hold.How can they release the money into the account that is on hold,so I really don't know how much long i must wait to get that money,their system is really not satisfying such a big company, they should stick to the old system whereby they will deposit your money into your own account because your familier with, their app is a problem. What's annoying is come month end they debit the installment without hesitation me I failed to do what I wanted to do with the money. The staff at the bank tried their best.African bank let me down, I'm very much disappointed.
