However, if you’ve already answered it (sometimes we tend to do that when a call catches us off guard), don’t follow any of the caller’s instructions. If an unknown user attempts to contact your Skype, ignoring the call would be the best thing to do. Fortunately, you can block Skype contacts you don’t like, as well as stopping unwanted calls, by following these tips we’ve pooled together.
