How to contact Verizon customer care for final billing related issues from outside US

[Meet2]

I have just received a bill for unreturned equipment however the same was returned through the UPS using the return shipment label provided by Verizon .The equipment was received by Taylor on 06-10-2014 as per the signed confirmation from Xbale . I want to email the confirmation receipt and get the charges reversed however I am unable to reach anyone in Verizon customer service.this is a case of pure harassment when the equipment has been returned long back along with confirmation of receipt , final bill generated and then being asked to pay for the equipment again
