I closed my account with XXXX XXXX in XXXX 2014. The effective date in my cancellation confirmation email was XXXX XXXX, 2014. Disconnect Order Number : XXXX. They continued to bill me for XXXX months after the fact ( XX/XX/XXXX and XX/XX/XXXX ). I confirmed with XXXX that my account was paid off in full when I canceled the account for XX/XX/XXXX. I just received a call from debt collectors today without any prior notice and they refused to let me speak with someone to XXXX to dispute the claim.
