Terrible customer service

This company was very quick to make promises and take R680 from my bank account, but they were so unprofessional. The first time a lady called me, she hung up because she could not spell my name, the second lady to call me was at least trying, but she never got back to me. I made a few calls thereafter, but I got no feedback. I then asked for my money to be refunded and was advised it will be done in 7 days. It is now almost 10 days and I have not yet received anything. I am getting no feedback and they are simply ignoring me now..
