Bad customer service

I have been treated very unfairly, i paid double amount end of August, a lady by the name of Shaume refused to refund my money R439, she said my account will be credited for 60 days, now my account has been disconnected, I just received a message that I must make another payment of R439, I have been sending messages via WhatsApp, they are not responding which means they are reaping off customers, I want them to refund my money, I will go somewhere else, I am too upset, I can't be dealing with them anymore.
