It's a fluke. You need to dispute it!
Something odd happened to me years ago. I opened up my report to report a demo. I opened it up and it was already filled in!
None of the numbers or information made much sense. I contacted the scheduler and it appears someone "said" they went to my location and did the demo. They did not. I did the demo. I do not know how they got into my report. Is it possible in your case, that someone "claimed" they did your shop and was able to report it by "assignment number" or there is some internal fluke that your photos got crossed over to another report. Since as shoppers, we deal with the internet to report and things can go wrong, you just never know.
But fight this OP!
