LOAN APLICATION DELAY

I began my loan application on the 28th of AUGUST, which i was asked to send some documents because some were not in order, so i did that and it was confirmed that everything is in order and the application is under review, that review began on the 31st of August, even today the application is still under review, I was promised a response in no more than 3 days, its been almost two weeks!! I've sent emails to customer service which were not responded too, I've call agents numerous times to assist me, none of them told me anything that was true. I do not understand what kind of customer service this is, I even went to the branch, who couldn't help me with the progress of the application, honestly it's better to reject me then make me wait for nothing, it must be understood that I did not apply for this loan for fun, this is the worst service I have ever received from a bank ,and i didn't expect this from AFRICAN BANK, given their values and promises they make to their clients, I've been stuck this whole time, ive almost given up on the bank entirely, im being very kind with this review, no company has made me run around like this bank did, and even if im just one client, its no way to treat me, this is unforgettable,im very cross with the bank ,
