Yeah you just failed, and if it was my country you would be reported to the Public Complaint Board and fined for probably breaking contract and false advertisement.
In America this is the way. Large corporations strive to be minimally compliant in all things. A small vendor would probably try to delight tough and do exactly what you wanted
Come live in Sweden! Most cities have a "City Net" which is municipal fiber. I recently moved apartments and the new place had both coax and fiber. I just went on an ISP website input my apartment details and two days later I had 500/500 Mbps for $39.14 / month.
