Hello,

I became a customer of customer>, and have had no problems with your
service. However, I recently billing> and found a charge of for period>, which is much higher than normal.

I suspect that this bill may be in error. I have not used your service
any more than in past months, and there seems to be no reason for this
excessive charge. Please have someone from your Collections department
contact me as soon as possible to resolve this situation.

Thank you for your time.

Regards,

Jim Karter
