********** Billing on my account

I received a call from the above-mentioned company, where a lady told me about the good deals their company has on holiday offers. She said all I need to do was to pay R1800, and my family can enjoy a discounted holiday in SA.I told her that I would like to have such a holiday, but not now since I have some financial crisis,may be in the near future. To my surprise I was shocked to see my account billed on the last day of November,2017.I have requested that this company must reverse that transaction with immediate effect,but even today, on the 5th day of December,2017,I am still waiting for my money.I am asking this company to reverse that transaction immediately,and stop doing that even in the future.I do not have an account with them,and I also not want any dealings with them. I hope this will be speedily resolved since I need that money urgently. Thanking you in advance Tebogo Mosetlhe
