I have yet to receive my payment for my test strips. I have never had any problems with my test strips before. I have been sending my test strips to the company for 2 maybe 3 years and I never had any problems before. I have sent Jeff Sheets an email on October 15,2017 and I haven't received any correspondence. On the the 16th of October I started calling the Chicago office and I haven't received any correspondence from them either. I would appreciate any correspondence from Jeff.
