cowboy green Promised that there lawn seed would grow grass on bare spots and shaded areas or I would get a 100% refund.

I purchased this product with a guarantee of a 100% refund if the product did not work. First of all it was to cost me $19.98 in Cdn funds then it was to be $26.57 in US funds and it ended up costing me $43.06 Cdn. There were two bottles included in the package containing a green liquid . When I sprayed the green liquid through my sprayer with water as directed I got nothing but clear water. I thought I would give the product some time to grow but after two weeks there is no sign of growth . When I contacted the company they said they would give me a refund of $6.00 US and I refused , then they offered me $3.00 I refused and then they offered me $9.00  and this would go to my bank account, they do not have my bank account . The last email I sent them was sent back as unknown . I paid the initial amount with my crediit card .
