<prompt> Human: Hello all. I have a child that is about to move up from daycare in to kindergarten on 98, I dropped her off this morning and got hit with a 4000 bill from them, I looked at it and apparently we were being undercharged for an entire year. The normal rate was apparently 220 a week which was reflected on the bill they gave me this morning, but the monthly bill that was being emailed to me was for 150, the price for daycare there changes constantly and gets lower as your kid ages so I didnt think much of it, especially considering she was too old to be in daycare but her weird age didnt allow her in public school yet. I was on time paying the bill and the balance based on the 150 a week was pretty much 0, if I had known I was being undercharged I would have brought it to their attention but now I am in a tough spot. They want it by 92.What can I do?  <response>: They can put whatever date 92 they want on the bill, but it doesnt mean you have to pay by then. Especially when the bill in question has a history of well over a 12-month span. So, ignore the due date for now. If you have the paperwork with the 150 bills, hold on to them and make copies. Look for any other contracts or pricing agreements you have signed. Did they change their rates mid-term and not notify you if your daughter has been going there for years, this is not uncommon or did you miss a communication about a rate change? Mistakes happen and like you said, you assumed the 150 was part of a pricing plan that gets reduced over time. Ive been to daycares that had discounts for long-term customers, sibling discounts, and similar. By all means dont jump to the conclusion that you must pay this all instantly. You need solid proof that this was the contract. So lets assume that their bill is correct, and they made a clerical error or typo on their bills. They shouldve noticed that long before 12 months went by. Id have a face-to-face conversation with the owner about this, with my printed out 150mo bills on hand, asking them to explain themselves. Mention that if they had raised the rate to 220 a week a year ago, you would have enrolled in a different daycare with lower rates, and similar. Perhaps convince them to split the difference or give you an acceptable payment plan. Document all of this. If the people are reasonable, they will work with you. If they are unreasonable, pay them nothing and consider bringing all of your information with you to court someday.
