Poor lead provider!! Stay away!

Poor lead quality and poor service.. very friendly until yiu pay them. Asked them to make changes to their contract which the agreed to over email and after I paid they said the changes are not valid and if I’m unhappy I can take them to court😳. Leads are not contactable with wrong numbers that I have to always ask for the correct numbers over and over. Or clients are not interested in appoints when you do reach them.
