Additional Notes

Complaint: I entered into a three year contract with Yarnell, and I have satified the three year agreement and it has been paid in full. Yarnell, has attempted on several different occasions to suggest that I entered into a five year agreement, which I have not, and Yarnell has suggested that an unauthorized individual may or may not have signed this five year contract. However, there is no Contract in writing, nor was there ever one for a five year term of service. All monies owed for the three year Contract that was in writing were satisfied and the account with Yarnell was inactivated on July 22, 2014, and no service has been provided by this company to myself since then. I have placed many phone calls to Yarnell, in hopes I would be able to obtain the disputed five year Contract in writing. Yarnell, however, will not, and can not provide this paperwork as there is no five year contract, nor has one ever existed. Yarnell, is now demanding close to $900.00 for said non-existing five year contract. This needs resolved immediately, as my credit is now being affected.

Desired Settlement: I want to have the money that Yarnell is claiming I owe for a five year contract, redacted and at a zero balance, as i have not had any services provided to me and I have not entered or signed any paperwork in regards to a five year contract. This is now affecting my credit and must be immediately rectified.

Business Response: Please retract any monies owed by this customer.

All charges will be credited to his account today.

Thank you,
