Planet Fitness Computer says I am wrong

I expect they don't really care about these reviews judging by their customer service staff but hopefully potential members do. I was a member of the Craighall Park gym which closed a while back. I was moved to Sandton Gate but offered the opportunity for a free move to another gym if that did not suit me. I elected to move to Wanderers and everything seemed fine. (Strangely they also told me I could use any another gym as well and at the time I thought that was great!) After a break from going to Wanderers for a while, I tried to start again but was told I was a member of Sandton Gate (again!) and would have to pay for a transfer back to Wanderers. After 30 mins trying to explain this error to their call centre agent (Pauline?) she kept telling me that the system says I am wrong and I must pay. Her superiors would not take my call. They really don't seem to care that I have been a member for almost 20 years and that my direct experience did not agree with what their system was saying (apparently it is "never wrong"). I think I am seriously missing out on a better experience at Virgin Active or frankly any other gym in the country.
