Yes and now this fee too!
I do have proof of purchase both with eBay and Paypal. I have texts offering to pay me £80 which never materialised, can't find the text that asked how much she owed me...however she has no proof of purchase or payment. I was going to give her a receipt when she paid the whole amount.
Do I have the right to turn up at her work, or at the end of the end of the working day and ask for the money, or to ring her firm and tell them the situation, or ask to speak to her on the work phone or would that be seen as harassment. She works for a solar energy call centre.
