Capital One Credit Card Complaint

Capital One Credit card department,

Customer service / Customer relations Utah

I pay my monthly balance to Capital One in full each month. Each month they hold my available credit anywhere from - days after receiving my payment. This month, I made the payment, then asked when funds would be released off of their hold. I was quoted -/-/-. After checking my account today, this is n't the case. Contacted Capital One again, and now in the period of the last 3 days they have changed the date my funds would be available from -/-/- to -/-/- and now -/-/-. They flat out lied to me, and then tried to cover it up. They claim that funds are held " At random '' but this occurs on my account every single month. When you try to get an answer they dodge the question and disconnect the call and/or chat session.
