fraudsters that is the only word to use

In May 2014 I was contacted by George Poolmann.He came to my house and told me that I can make 40 % profite when I am using the software and information provided. He said I can cancel anytime the contract and get a full refund back on the software and monthly payments if I am not happy.The technician came 3 weeks after I paid,came with an illegal microsoft version and installed it.The software is not up to standard and it did not work on my system, kept informing them, but no reaction.Went to their office in George and tried to cancel the contract,but Mrs. Poolmann told me that another man tried to make \problems"and haven't had success with it and I am more than welcom to go to a lawyer. I wrote the head office about 20 mails"
