No Feedback of application

i am not happy of the way things are being done at African bank i app**** for a loan on Tuesday signed the contract and even got a slip saying its approved now my main concern is the information that i was told at the branch after my application was approved that i would receive the funds the following day i waited and nothing then i called the customer service consultant which i forgot who her name was and she told me that its still waiting to be approved and that it takes 48-72 hours which that was a shock to me then today i called again and another consultant said they have a back lock and will attend to my case in the next 24 hours now if i knew about this i would have seeked help else where and would have received the funds the very next day now i have to wait until God knows when to get the funds and the funds where needed yesterday latest and if i did not call they where not going to inform me about the back lock this is disappointing especially that i always pay my account on time the only time i had an issue was in 2013 when i lost my job but i made an arrangement and i have settled that loan and now left with the arrears but i have never skipped a payment since then.
