Wells Fargo XXXX credit card approved me a promotional offer of no interest if paid in full within 18 months. Half-way through the terms I noticed the company was not charging me equal payments but slightly lower payments to ensure that I would be required to pay the full interest amount at the end of the term. After noticing this, I put down several large payments to remove the balance. The balance was paid on time before the end of the promotional period but I was still charged the {$4000.00} in interest. During a phone call to the company, the representative stated that my last payment ( {$370.00} ) was partially applied to another purchase ( amount of {$290.00}, to a balance of {$850.00} ) instead of paying off the remaining balance of the 18-month promotion ( {$230.00} ). The representative said that the terms I signed up for did not state equal payments nor were they required to expend the minimal payment amount to the oldest promotional balance first. This is a predatory tactic aimed to trap the consumer. Please resolve.
