They are sending me emails daily after I have asked very politely to remove me from their mailing list as I never signed up tonreceive anything from them. There is now 3 people from this company who is sending me emails daily!!! How desperate…. This is against the law of my rights in SA! I have repeatedly requested them to remove me from their mailing list as I never signed up for this. Totally unexceptionable!!
