Unprofessional behavior by gohealth Durban north

We have had numerous meetings with gohealth management, in regard to renting out thier studio and opening up a kickboxing club. After 3 weeks gohealth management said they will charge us, R5500 a month and advertise for us by sending out an email to all members informing them of our class's, I agreed and requested for a contract. Gohealth said we can begin training in the studio and the contract will be handed to us by the end of the month. They also gave us a go-ahead to start our advertising.

After three weeks of training students, the manager says sorry but the managers from Johannesburg, have changed the rent and increased it R7200 and reduced your time in the studio. I asked how is the possible, his response was they said it's either you accept it, or leave and all my advertising cost were lost.

This is unprofessional behavior from gohealth Durban north.
