Agent didn't include us in best and final offers

[stroopwaffles]

We offered 10k over for our initial offer on Monday. Told to expect best and final that afternoon.

Rang on Tuesday for an update.. hadn't heard anything from the vendor.

I just checked Rightmove and the property is STC?!

What should we do? / Is there anything we can do? I thought agents were legally obliged to pass on any offers to the vendor. Can we post a letter saying we offered X and were willing to go to X but weren't given the chance?

I don't want to gazump though..

When we bought, we'd already lost out twice at best and final, so we just went straight in with our (significantly over asking) best price, and we got the house. I believe there were 14 offers! We figured that it would definitely go over so if we could get in there without giving others the chance to raise their bids, it would give us a better chance - and it did. I expect the same has happened here.
