I Have Two CD's With This Bank

I have two CD's with this bank, and the first one was opened fairly easy - The second, being funded with $10,000 at a 3.15% rate took over 2 weeks for them to open and then they opened it at 2.75% - They say the rate is at the time they fund the account.   They ignored ALL requests for a status until they lowered the rate and now I am stuck losing .5% for 5 years.   Their customer service can really suck.
