Has it ever happened to you that a webmaster removed a backlink without warning you?

have you ever dealt with the situation when a webmaster removed backlinks from an article without warning you? What did you do?

Don't ever buy with "it's good to be true deals"
They promise you and give you link but with few days link is gone and they don't offer any guarantee
Try to get a refund from the seller or contact webmaster for the deal
