Capital One Credit Card Complaint

Capital One Credit card department,

Balance transfer Texas

After talking with multiple departments to combine my capital one credit cards to lower the interest rate, today I am frustrated with a customer service rep who addresses my concerns, with Oh my god '' after I respectfully ask to speak to a manager. I was told that I could combine my credit cards from Capital one to the lower interest rate almost 3 weeks ago and that I would receive the confirmation in the mail, today -, employee ID -, supervisor that informed me that nothing could be done and the previous representatives was wrong. My complaint is gross miscommunication, unprofessional behavior, failure to provide accurate information/plans a consumer can participate. Speaking to a customer in a unprofessional manner such as I was today. Totally unprofessional and uncalled.
