There are a few current problems here.
One is fairly obvious - FTTC means "Fibre to the Cabinet" and you are not connected to a cabinet.
The rest are to do with why they haven't found a way round that yet.
Starting with the first problem, no cabinet. The fibre service is added onto your telephone line in that and carried over the existing copper from there to your house. See here
for a fuller explanation.
They can't add the fibre service to the DSLAM which supplies you in the exchange. Either it doesn't have the necessary connectivity, (the ones in the FTTC cabinets are designed specifically for the task), or it is simply to prevent the bad effects the service would have on other services from that exchange. Technical reasons in other words, that I don't know anything about. OfCom has issued regulations about this.
There is also the point that many exchanges that are "FTTC-enabled" don't actually supply the fibre connection. They continue to supply the phone service, but the fibre one is supplied from a different exchange and gets onto your line as already explained.
Apparently Openreach are looking into this issue for the longer term, but the push and money is going into the easier mainstream rollout at the moment, so as to meet/exceed the coverage targets. Two solutions that seem to be around are to supply FTTP instead, or to install fibre and phone cabinets to replace the current exchange supply to people such as yourself.
Another issue is the question of why you are EO. If it is because you are close to the exchange then the solution is likely to be different from that if you are on a new build estate at a considerable distance from the exchange, where it was cheaper/easier for Openreach to supply direct than to install new phone cabinets when you got a phone service in the first place.
