Bad service

I am a member of Zone Fitness in Campus square i gym in the morning 6:30 to 7:30 before i get the work. In the month of April the company debited my account meanwhile we were in lock down level 5 since March, when i enquired they said i can bring someone for 3 months free gym as courtesy for the debit. its been two weeks since i've been enquiring everyday what is needed for the transaction to go through and have been getting the same feedback that i need to bring the person in who wants to join for the free 3 months. Yesterday which was the 11th of November i went with the new member ,his ID and the R 50 they required so that we can proceed with the promise they gave us and when we arrived at the gym everyone acted surprised as if i started the story of the courtesy membership and Nombeko who i was referred to refused to assist me and my partner with a very bad attitude and walked away living us at the entrance frustrated. She said she is not a sales consultant , i must wait for sales people to come at 9:00 of which i must be at work at that time. I suggested that they give me the membership form so that we can fill it in and the submit it to the sales people when they get to the premises and she refused and said there is nothing she can do ….. i am really disappointed in the service received.... How do front desk people have so much bad attitude and inconsiderate of their clients time.
