******* Business practice

I have been a Virginactive / Vitality member for a number of years,I am now on a month to month contract. My dependent on my contract is now at University and lives at hostel, therefor he will no longer be able to use the Gym. I have contacted the cancellations department to cancel his membership as they placed him onto a premier select Adult membership without my consent costing me more than R600 pm. It is the 30th of Jan and my debit goes off on the 1st of Feb but I am told by the cancellation department I need to still pay for him for the month of Feb even though he will not be going to the GYM ????? How ? What ? Where ? How do you explain this type of business practice ?
