Unfair loan process and dysfunctional customer care

So I need some quick cash not a lot of money because I was skeptical of my repayment premium. I app**** with TymeBank and approved for a large amount of money. Unfortunately their application system doesn't allow a client to adjust the amount they need which eventually affects the repayment. I took the large amount with the intention to use the portion I need and return the one I don't need. Guess what I returned the extra cash with the intention to reduce the payment Unfortunately I am told the repayment amount cannot be adjusted, So I'm stuck with a high repayment amount that I cannot afford. Your customer care is the worst I have ever met, There were days I waited over an hour to be answered and gave up plus not to forget it's not even a toll free number. It is clear from my experience that the loan process nor customer care are far from being fair or user friendly, in my case it did not serve the purpose at all it ended me in a worst state compared to the way it found me.
