If you read witchunt's comment again the OR commercial rollout was for FTTP not FTTC so OR was never planning to upgrade your cabinet.
I read witchunt's comment but it was so terse I didn't really get what they were trying. Based on your interpretation though then unless they have something to back that up then it's flat out wrong.
Here's a simple question to understand why... Why would OR look at every other property around us that's in the commercial roll-out area (and it's a big area) and upgrade them with FTTC but then look at out cabinet and think "hey, just for giggles let's do FTTP for these flats" ?
It wouldn't make any sense and was never going to happen. The only way that would have happened would have been if we were on EO lines (we're not), someone was paying for it (no one was) or they misidentified our address (this I might believe). Other than that there is just no way that OR looked at our cabinet and thought "hey, let's do the more expensive option for no reason whatsoever", it wasn't going to happen.
