Services are provided on a month-to-month basis and clients may cancel their service at any time at least (3) three days in advance of any upcoming recurring payment. When services have been canceled according to these terms, the upcoming recurring payment will constitute the final payment due for services rendered. All services are billed in arrears. We do also provide a 120 Day money back guarantee. If we do not produce any results or any deletions, we return every penny spent with us. We just ask that you provide a copy of your report when we started the process and a current report as well. SIMPLE!
