Worse Terrible service

I have never experienced such a terrible service like the way I had with African bank this week, they are behaving like I am doing application for the first time with them. I made a application for a credit on Monday for loan, after that I was told to submit supporting documents as they have mentioned and to the email adress as they said, I sent the documents three times but still they keep saying that they never received documents, I fail to understand how come because it's the same email address that I was told but there is no feedback, it's been more than 48 hours waiting for the feedback, they wasted my time of waiting, if they told me once that they cnt help me than delaying me so long like this, if I knew I should have gone try somewhere, they are been unprofessional and ******** for their clients, I wonder why such a terrible service because all the accounts I had with them I paid them up without outstanding, I feel like they wasted my time, it's been three days without without feedback, this is worse than ever, I never expected such from the institution I settled all the accounts with them, all the information they keep asking me I did send them but no feedback. Why African bank becoming a terrible institution like this? Is it having new management or it's their poor system or illiterate consultants who cnt do their work? I have app**** credit before, I was rep**** on the same day but this time is been more than 48 hours with excuses of missing documents that I sent three times. I am so ****ed because they wasted my time with no service at the end. If they ddnt want to help me they should have said it than wasting my time.
