Lack of service and levels of complete incompetence!

After closing my account more than 2years ago, I received a message that my account had been handed over to collections. Called customer care and after being transferred from 1 *********** agent to about 3 more, I sent an email. Received a reply that someone would contact me within 8 hours. It has now been 10 DAYS and still no contact from them. Meanwhile I am receiving messages from the collections company that I owe them money FOR A CLOSED ACCOUNT. This is why I closed my account after almost 14years being their client. I am going to the ombudsman. I will not have my credit record suffer due to incompetence!
