Gym Trading Specialist - Bad service and commitment

Re: Customer Services of Gym Trading Specialist - Le Roux Ave, Halfway House, Midrand... I've been interested in a spinning bike and made a commitment to buy it. The owner told me they had to fix a couple of things fist. After a couple of weeks he started ignoring my calls and I received no response from their end. They don't answer my calls and don't answer my whatsapp messages either. It's now almost 2 months with no feedback. I'm disappointed in the service and commitment.
