Acima review: Car repair

I was introduced to Acima by a friend of mine when I needed car repairs done. I used them once before and ended up paying them much more due to missing the 90 day pay off. On January 31st I fixed my vehicle which cost 2830 dollars purchase. I missed the 90 day early purchase and continued to make my biweekly payments. I was told my total cost would be 5095 dollars. On Monday November 27th, I checked my account and I owed a total of 907 dollars with an early pay off of 436 dollars. My next payment was due on 12/1. On 11/30, I called to make the pay off amount of 436 and was informed that I could not. My regular payment of 209 due for 12/1 was already being processed and my new pay of amount was 349 plus tax. This meant that instead of 436 I would be paying 570. I asked if I could just pay the remaining 238 to make the 436 since my due date was on 12/1 and the payment was not completed yet. I was told that I could not and was also told that the payoff amount changes daily. I was told I would have had to make my payment two days before my regular payment was due. This was not explained before. I was only told it had to be before a regular payment went in. My question, why would you change the payoff amount before the next regular payment is made? For instance, my regular payment is due tomorrow and is already being processed and a new pay off amount is set at 349. That payment amount should stay at 349 until after my next regular payment if I don’t settle the debt. I will pay the amount stated but I do not recommend Acima to anyone.. I have another open lease which I will pay off before the three months but will be staying away from this company.
