Taking loans with high interest is suicide. I am not good at taking loans but when I have no options left I ensure I take the ones that won't be a burden to me. From 68k to 92k, come on, that interest was much. Well, sometimes, I am not necessarily bothered about the interest but what the person used the money for. It will hurt more if you take a loan with that much interest and didn't do anything reasonable with it.
Those loan app guys are something else. The can go any length to embarrass a person. Their approach to getting back their money is bad, how does calling all the person's contact now make the person refund their money? Look at the case of your sister, after the nonsense calls and texts she later paid. But they didn't call the contact s back to notify them that have has paid. They should find another strategy abeg.
