Prepaid plan 25$/month - Obtain a bill
I am currently using an AT&T 25$/month prepaid plan. I actually paid 300$ for 12 months in order to benefit a discount on the offer.
I would like to get access to a bill to prove that I am using the line associated.
Where can I obtain such a bill? There is no information on my AT&T prepaid account and it's impossible to contact your services by phone call.
