Product: Credit reporting, credit repair services, or other personal consumer reports

Hi, on or about XX/XX/2019 I received several alerts from 1 of a few monitoring services that I have to monitor my credit, that my score had dropped. When I checked to see why I was alarmed to see that my score had dropped 81 points. I first noticed this on my XXXX  report from my XXXX  account. I checked my paid subscription and noticed that the same loss was reflecting not only on XXXX but my Experian as well. All of my scores prior to the drop were 800 and above. I did not pay anything late so I called XXXX  to inquire as to why I lost so many points. I spoke with several representatives over a 3 day period. Essentially, there reasoning was that because of the credit card that I'm a authorized user of, note that the limit is XXXX, the initial balance that was being reported before the score drop was around 8k, was charged up to XXXX  was the their reasoning. I did not mention to them that in my profession I virtually see credit reports everyday and never have I witnessed a drastic drop in points like mine unless there was a collections account or a bankruptcy being reported and that I have neither of those. I had just witnessed a relative who had 2 30  day lates reported around the same time that I witnessed my drop in points and needless to say, the gentleman was not penalized nearly as much as I was. We used the credit card, it is not late but someone else can have 2 30 day late payments and not lose 81 points on their score is baffling. I feel like I'm being penalized for the area that I live in that is more of a minority area than elsewhere and had my zipcode been from another area where credit scores tend to be higher then I would have not been penalized as such. This event has caused me great anxiety and stress. I'm scared to open a email about my credit report for fear of seeing that my score has dramatically decreased because of an inquiry or because we have used a credit card that we tend to keep under 30 percent utilization which the credit bureaus have put out info saying that as long as you do this then generally it benefits your score. I'm not sure of what to do because the bureaus seem to have broad discretion but no set parameters as to how they grade a persons file. In sum is that, why can a person have 2/30 day late accounts and be penalized 51 points but I have a increase from XXXX  to XXXX on a credit card, not to mention, the balance was paid down a day or so before I received the alert of the score drop, but I've lost 81 points with no late payments? This is extremely depressing and I don't know what else I can do besides report this to you and hope for some help. I was a XXXX XXXX several years ago and I've seen thousand 's of credit reports and never have I witnessed a 81 point drop because someone increased the balance on their credit card. The closes scenario that I can say may have cause anything of the sorts would have been a bankruptcy. Not even a collections account have I witnessed would do this. The representatives can give my know viable explanation for the drop. Please help me to get some logical rational concrete reasoning for this so that I know when and if I can ever use my credit. Credit is  very important and I try to keep mine 's above the average in case of any emergency 's but right now I'm scared to do anything for fear of the bureaus over penalizing me. Thank you for your time and consideration with this matter.
