The answer is NO, according to Walter A. McDermott, owner of the telephone auditing service that bears his name.

"I have been reviewing the phone bills of business firms since 1968, and it is astounding that we still uncover overbillings in approximately 50% of the cases that we work on".

WHO WE ARE
We are an independent auditing firm trained to uncover hidden overbillings of the various telephone carriers. Our practice is devoted to the recovery of refunds and elimination of overcharges for business firms of virtually any industry. Working on a contingency fee basis, there is never a cost to our clients who do not receive refunds. To maintain our independence as auditors, we do not sell any products or services.
All work is performed by our trained staff, and is not subcontracted out. Combined, our senior associates have over 110 years of service with our firm.
The range of refunds can be as small as $150.00, and some refunds have exceeded $1,000,000.

Two benefits of a successful audit...
