Cancelled service still gone to collection

Att/direct tv account [EDITED]. Put on vacation hold for indefinite time, feb 2018 and it never got done by direct tv . I moved away and no one was at my house .I returned equipment called and paid 2 more times after closing account just to be able to talk to someone. The last man I talked to said he could  lower my amount owed (for no service or equipment) if I agreed to another 2 year commitment. For service in a vacant house while I am in another state. Now I am in collections for same said service that I do not have.I have spent 11.2 hours trying to clear this up since April 2018 to no avail . Now you are damaging my credit and again today I cannot reach anyone.  My acct number was [EDITED]and Afni collection acct  number is [EDITED]1.
