WVP International — Deposited Fees Rs 75000/- plus GST not refunded

I have registered with Canada PR as Ms Ishika-an employee of WVP offering attractive benefits with low IELTS band and deposited Rs.75000/- plus GST after confirming that deposited fees are refundable as tax invoice is marked with REFUNDABLE(enclosed herewith). After one month I enquired & realized that it is fake then I call to Ishika([protected]) & asked her about my money. She totally denied that she didn't know about any money. Then I was trying to contact to case manager -Ms Anurama, She also not responding properly then last week I write an email that I want to discontinue their services please return my money. Then immediate they called me that you can't email like this. I have requested a lot but they are not agree to return my money even though the Tax invoice is self explanatory by writing a word REFUNDABLE on each issued Tax Invoice. Please help me to get my money back.
