Capital One Bank Account Or Service Complaint

Capital One Bank account or service department,

Checking account Account opening, closing, or management Maryland

On - -, 2015 Capital One - branch representative opened a business spark checking acct for me. I showed him a promotional offer $250.00 at acct opening in branch. The offer says open a acct with - and make a - bill pay within 30 days, then $250.00 cash bonus will be credit back within 6-8 weeks after promotion ends. I made deposit of $5800.00 at acct opening, and made - bill pay $830.00 on - -, 2015. However I never received $250.00 bonus, also the bill pay was stopped which caused me extra fee $70.00 from the payee. I never asked the bank to put stop payment. On - - 2015 when bank rep called me several times I asked them to release the payment. I am asking 1. $250.00 promotional bonus back plus $70.00 fee caused by the bank. Or 2. bank can issue a letter to payee to waive this $70.00 extra fees. But $250.00 promotional bonus must be credit back.
