Telecommunications carriers amend terms of services from time to time. They provide change notices to customers via postal mail, printed on an invoice, or as an electronic alert in a billing portal. Reading and understanding each terms of service change is an important vendor management activity for customers. One such change posted by AT&T in December illustrates why reading these notices is important.
Effective January 14, 2019 AT&T will no longer offer prorated credits for services cancelled before the end of the billing period. AT&T bills in advance for DIRECTV, U-verse® TV, AT&T Phone, AT&T Internet and Fixed Wireless Internet services.
