I got my refusal on a Friday, my husband who was already in England sent me documents containing sponsor letter, appendix 2, tax returns, and pictures via DHL on Monday, I swung by the bank on Tuesday for updated bank statements, did the online application on Tuesday, put together relationship proof and typed letter stating what proof I had gathered, had biometric appointment set for the following Monday, but went in 4 days sooner on Thursday where they accepted me as a walk in, and sent the whole new package to Sheffield exactly 6 days after receiving the refusal. I only spent one day wallowing, I just wanted to get on with it.
We were successful, but I will say, even though I worked it rapidly I was very very careful.
