Well I will try to give the OP some encouragement to name the SP when he's next online.
I imagine that they are well versed with this site and will know the type of reaction that you get for a vague, whiny post like this. So the motivation is either to genuinely inform the other members - in which case, name the girl in the next comment - or it is to generate a response from the SP herself directly with him by threatening to make accusations here - in which case no-one is interested.
So this OP has come very much to a fork in the road in their UKP experience - tell us all who she is (and be prepared to provide follow up details) or pretty much fuck off for good, as you will have no credibility whatsoever. Over to you OP ....
