bad servicee

On 13 February I went to Virgin Active in Vodaworld to enquire on my son's membership, I was assisted by a guy called Kenny. My son turned 18 on 1 march 2016, I asked Kenny to confirm if the debit order for the month of March will still go off, I also indicated to him how important it is for me to know in order to make arrangement for the money to be available. He promised to get back to me latest on Monday as the offices were closed, I am still waiting for him till to date. I went to the gym again and asked the lady at reception to let him know that I am still waiting for him as she was there the day I queried this . I am very unhappy with the service I received from Kenny Vodaworld branch, I feel that I have been inconvenienced. I got an SMS from my bank notifying me of the debit order of R 596.00, I did not have enough time to check at the time. I made it clear that I want my son's membership cancelled at the end of February, reason being that I did not have the R 1 590.00 joining fee to pay when he turn 18 and do not want to owe virgin active. Why deduct R 596.00 for my membership only, can somebody clarify this. Since I joined virgin active I have never receive good service, d
