We've just made the final payment on our house and have our keys. We were walking through when we realised that some of the electrical work we'd paid for hasn't been installed (for example we got normal lights and switches instead of the upgraded ones we've paid for).
We got in touch with the builder and told them, and said that we'd like a refund. They are however refusing and are insisting on sending someone out to rectify the issue.
We've had multiple delays getting our keys and don't want yet another one, and we also feel like the advice we were given regarding the upgrades was incorrect in the first place as the basic fittings we have are perfectly fine.
Do we have a legal leg to stand on to refuse the rectification, and insist on a refund of the difference in cost of the products installed from what we paid for the upgrades?
