Feedbacks

[Viviene]

A couple of months ago I completed a booking, punter was happy, asked about a future booking, the next day I sent good feedback, now in the last week I have been receiving text messages from him saying he is going to get my profile removed, leave bad feedback, generally hassling me, what's best to do, just block his number?
at this point in time he has yet to submit a Feedback two months down the line.
Can I withdraw mine if he continues to kick off?
Should I contact AW ?
