Citibank Mortgage Complaint

Citibank Mortgage department,

Other mortgage Credit decision / Underwriting California

We were trying to refinance our mortgage. So after talking with multiple lenders we decided to go with Citi Mortgage based on the GFE they provided which has $5000.00 as lenders credit at 3.000 % interest rate. However, 20 days later when interest rates went up, I got another letter email saying that they recently received new information and sent me a new GFE which has lenders credit reduced to $1000.00. Now I ca n't even go for new mortgage shopping as the rates have gone up. If they would have mentioned the same before I committed to go with them, then at least I would have had an options of going with next best option.
