False advertising and bad cancellation services

I would like to cancel my membership with Planet Fitness/Just Gym with immediate effect.

I singed on Sunday 6 October 2019.

My children showed me that there is free membership for teenagers with a main member, I went to the gym in Vanderbijlpark and enquired, they said unfortunately their gym was a small gym and do not offer that promotion, but, I was told I can have my children join me for a seven day free trial, age was not mentioned, so I signed up and paid the first 3 months upfront. The first day we were there the two boys were signed up for a seven day free membership. The got a one day pass to gym on Monday. On Tuesday we went to gym where I was told that the boys cannot go in with me because they are not 18 and do not qualify for a seven day membership but only one day, which they had on Monday. I took membership because that is what my children wanted. I am disappointed that this is how it turned out. You have not lost only 1 membership, but 6 memberships. 3 Adult and 3 student memberships.

Now I want to cancel membership, the call center system is offline, and emails are responded to within 72 hours. I have a 5 day cooling off period and expect to be helped as quickly to get out as it was to get in.
