Poor service - Membership cancellation

I opened a membership on the 25th May 2019 and cancelled it the next day the 26th May 2019. The sales consultant Hector( Location : Bloed Mall) confirmed the MSG received and said "no problem, I'm not at work today" . When I went to fetch my 100 , they said i must pay a cancellation fee of R1400 something don't know the exact amount. As per contract the membership cancel be cancel within 5days after registration, which means the consultant never cancelled it. Very poor service from that gym. No friendly staff.
