Priority International — no single service from priority

I took membership in priority international in jan 2016. Its been more that 3 years i didn't get any service from p. I. Moreover it, s been promised by this company that i can swipe my credit card and convert it to emi and interest amount will be refunded by the company. I paid around 115000 inr and paying interest amount of credit card as well. I have sent more than 100 emails to this company but they always say will get back to you soon from last three year. I am fed-up with this company now.
