BLOCKED FROM NETWORK DESPITE HAVING PAID A MONTH AHEAD! NO HELP, FCC COMPLAINT FILED

To say I’m angry at AT&T is an understatement. After 20 years, I left AT&T for Sprint last September, service was awful, I paid my device off in full and came back to att June 2019.  Had NO problems with my phone or service and then September 15, at 4pm, no network. Said I was blocked.  I came back and did prepaid, so I am paid thru mid October with AT&T and Asurion. I call At&T asking why I can’t use my phone.  They tell me my phone was reported stolen.  The person at the store told me it was blacklisted. I called and spent 2 hours on phone with Sprint, had a conference call with AT&T and sprint. Sprint repeatedly told them they did NOT blacklist me, I paid In full and was free to go wherever I wanted. Att told them they showed them blacklisting my device. Sprint told them “we can’t remove a block because there isn’t one to remove!” Sprint assured me all was clear and they couldn’t control what att saw on their end. All IMEI reports were clean and good. AT&T’s final word was “we can’t help you”. Eight hours spent on this. Customer of 23 years. I’ve had my # 20 years and if I lose it over this I’m not sure what action I’ll take. I’ve had to go to Verizon who set me up a month of service (funny. No IMEI issues there?!) prepaid. So I’ve now spent $80 and $55 for services, of which the $80, I’m not allowed access to. Will I be refunded for them denying me access for something I paid for? No.  Att tells me to call Asurion and file a claim. I called, woman said “this is weird.. you’re paid through October your policy is good but it says suspended?”  Oh! More $ I paid out I’ll never see again. No one, NO ONE, will help me.  No one gets management when I ask no one would let me talk to someone who could help.  I can’t even find an email to send this to because AT&T treats their prepaid customers like step children. My time and stress has been ridiculously high, I leave the country in 2 days and anyone who has ever needed me, can’t reach me now. SHAME ON YOU AT&T FOR NOT TRYING OR CARING ABOUT YOUR CUSTOMERS. Hopefully this gets some attention.
