Abacus 21 is in the process of transitioning its Telephone and Internet Services from AT&T to Verizon.

During the changeover (which will be done over the next two weeks), we might be experiencing some interruptions in our 800-Services, Website-availability, or Email responsivity. If these do occur, we are anticipating the disruption to be brief.

If you have trouble with our 800-Sales Line (800-544-7310), please call the regular number of 716-873-2155.

If you have trouble with our 800-Support Line (800-529-8515), please call the regular number of 716-873-8515.

We apologize in advance for any inconvenience that you may encounter. If you have any questions, please contact Abacus 21 Support.
