Dishonesty in pursue of a sale

I was called by Thuli at Virgin Active Vanderbijlpark about a promotion running in December that my colleague sign to. She told me that il be paying 553 for me and my son for the duration of 12 months. My colleague confirms that her debit was 553 and mine 683 that’s for the two Debit orders so far. I get paid on the 20th and surprisingly I saw a debit on the 1st of January, leaving completely out of budget. I send inquiry to the club and to the consultant Thuli. A day later I received a call from Thuli bribing me of a 1 month free membership after asking why she gave me false information in persue for a sale. She still can’t advise me why I’m paying extra for my son. I’m really disgusted by her service and dishonesty. She should also stop harassing me by her consistent calls. I don’t feel comfortable with continuing with the business anymore. I just want to cancel and go to another fitness club that actually cares for its clients
