I know you have many customers but you make us feel as if we are your only one.
We've been extremely happy with the quality of service we've received from Granite – migrating 3,000+ phone lines plus the installation of new data services at over 900 stores. The single point of contact culture at Granite is the best in the industry and billing is, by far, the easiest and most transparent.
