Presented seminar - not paid yet

I presented a VAT seminar to the Cape Sun and was approached by Instance Consulting to do it on their behalf in November 2014. After various emails going backwards and forward I have yet to receive my payment. It was my time and the seminar notes that I have to print and provide to the people. Every time you phone no one is there or the accountant is there.<br> <br> People watch out for them as you might be approached to do seminars for them and then never get paid.
