Pathetic service- Planet Fitness Lynwood

Purchased a Hyperli voucher to train at the Lynwood branch for 3 months. As usual Hyperli asks you to present the printed voucher in order to redeem. I did that but the Gym staff including management had no idea what Hyperli was. After a lengthy back and forth with the Gym staff and the manager the manager decides to give me a 7 day free trial until he can verify that the voucher is correct. Firstly as a customer I shouldn’t be telling the company what specials they are currently having, secondly coming from management to say they need to “verify” the voucher is simply pathetic. For trying to support a company I felt more like I was being investigated for no good cause! Pathetic service! Management if not all staff should be clued up on their current specials.
