Dissatisfied with the level of service!

Good day, my loan was approved 4 February 2020, the lady assured me that the money would be paid into my account that afternoon. Up to today, 13 February I have not received anything? Why did she not inform me at the time that there were some technical problems and that they are running behind? I would have immediately looked for another solution? You take out a loan, because you really need the money! When will I receive it, as I only get vague answers to my questions. A day, a week, a month from now? Meantime the contract will go on as normal, at the end of the month I must pay the premium on the day, in time! How does the interest get calculated from the day your contract is approved, or the day you actually receive the money into your account? Please can I get an answer, a date, a commitment as to when exactly I will have the money in my account?
