Poor service

This is specifically about the Brackenfell branch. The service after they have signed you up is pathetic. I had a wrong amount debited from my account twice. Contacted Nick who is a sales consultant and he just stopped responding to my calls and what's app message. I have requested to speak to the club manager, but in the month and a half she has not even bothered to return my calls after leaving message with reception. I have also tried to talk to the sales manager David and he also stopped responding or answering my calls.
