Texas Confiscating Offender's Grievance Operations Manual

Not too long ago I purchased from y’all the Offenders Grievance Operations Manual, which I paid about $10 for. I need y’alls help in the sense that if y’all could please send me any kind of proof that I did purchase this manual from y’all. Or if you could please send me a witness statement that I did purchase this manual from you. The reason that I need this kind of proof is because said manual has been confiscated by a C.O. that works in the law library. And it would help a lot if you could please help with this matter. I thank you so very much for your help in resolving this matter. I will wait for your prompt response. I need this information as soon as possible so I can file my step 1 grievance. Thank you!
