Product: Credit reporting or other personal consumer reports

My Equifax score dropped to XXXX even though I have nothing derogatory on my report. I have the same high credit card balances that are reported on my XXXX report, and my XXXX score is XXXX. XXXX reports my oldest account as XXXX XXXX XXXX while Equifax reports my oldest account at 15 years because there's an old car payment listed from XXXX  ( also paid 100 % on time, and close/paid XXXX decades ago ), so my score should be a little higher on Equifax than XXXX based on that. All three of my reports were in the same range until the last 2 months when my Equifax dropped like a rock. All reports have no derogatory marks, with 100 % payment history. 
Our business was declined for a 7 ( a ) loan because this report dropped my XXXX XXXX points below XXXX 's minimum. So I called Equifax to ask why my score is so low and they told me to call a credit advisor. I'm XXXX XXXX XXXX - I know what my credit score should be. They told me that the scores are calculated differently and that's why my scores are different. I told them that I found a page on Equifax.com that says how each factor is weighed and the percentages are an exact match with XXXX 's, and however the algorithm differs, it's not a XXXX point difference... it's always been in the same range until now, but they wouldn't listen to me. A " low '' score is not for someone who has 100 % on time payment history for DECADES. I have all the same credit debts on my report as my husband has and his score is higher, and his oldest accounts are newer. I explained in every possible way that I could that their algorithm is weighing my factors wrong, that this needs to be escalated, while they told me over and over again to call a credit advisor the whole time. A half hour later I finally got another phone number to call. The 2nd guy at Equifax also told me the same things but it only took me 20 minutes to get him to tell me he would escalate it so someone would check the weighing algorithm to make sure the score is computed correctly- which is exactly what I was asking for. He said I would get a confirmation email, and I never received a confirmation email - so he was just trying to get me off the phone. If he really intended to escalate it to someone to check the algorithm, he would have just done that when I asked and the call would have been 2 minutes long. 
We need this addressed right away because our business needs our SBSS corrected. We have been growing our business for 8 years, meticulously and flawlessly so that when the opportunity to expand into the perfect location arises, which is NOW AVAILABLE, there would be no obstacles. Yet here we are. Both XXXX business credit score anXXXX XXXX XXXX XXXX are reported as " excellent '' for our business, all good and nothing bad, just as we planned it, but our Equifax business score is sitting there saying " low '' in RED with a score in the XXXX, with absolutely nothing derogatory reported on it. And it says one of the " score factors '' is " evidence '' of late payments or charge offs ( and we have no such thing! ) and there's nothing negative reported on the report that explains that being a factor- it's all positive and it always has been, as it is across our others. There's nothing derogatory reported because there's nothing derogatory to report. The statement is entirely erroneous and isn't based on our credit report. This is a different report than my XXXX personal score, but the one affects the other - and there is no derogatory report on either, or on any, and no unpaid accounts, late payments, or charge offs exist. And since there's nothing derogatory on any report to dispute, there is no process for me to address it besides being shrugged off and condescended on the phone, so no, there seems to be nothing I can do.
