Unfair Billing - Unhappy Client

For the year 2026, I re signed up my daughter to be a member and noticed that the fees are much higher for both my daughter and I. Last year I paid R280 per month for my membership, and this year I am paying R336 (daughter) R347.50 for myself. Now please explain to me why my partner who is under the same membership with his son at Randburg is only paying R280. Same company, different rates, but yet Little Falls has the oldest equipment, power is constantly off, and they change classes and coaches without asking the member's opinion.
