I think the problem is not about the “extended quota” part but about the fact that your record number 27 in objectID = 151 is too big. As stated here , all records must be lighter than 10kb (10 000 bytes).
Your record is 56 897 bytes so that why it’s refused. No plan can change that so I guess the “Contact us […]” part is a generic one.
Please tell me if it helps
