Steam Error

Hello guys i got this error " The current payment method does not match the country of the store" I did put Euros , But since my country doesnt use euros i think there might be a problem . I wanted to buy cs:go really a fan of CS games . But steam now has to do this ? Like they dont want my money ... I already contacted support . 4 months ago , they are "working" on it ... Can you please help me . Thanks Alot
