I had been a Vantiv/Mercury processing customer for about 2 years and decided to switch processors due to multiple reasons. One of the driving factors was poor implementation originally, poor customer service and high fees. I cancelled the account in writing and they slap me with a $495 cancellation fee, a violation of the contract. They will not even speak to me about the dispute but sent T&C's that were not the same I signed stating that I didnt give 30 days notice to cancel. This is completely incorrect, they are frauds, terrible to work with and would never consider Vantiv again. Everyone should stop working with such a pathetic company and force them out of the business.
