Non Payment for equipment sold

I had been dealing with dive locker for many years, booked training, recommended training (including my daughter) and other friends of mine. Booked accommodation and dives. I had stopped diving and decided to sell all my dive gear through dive locker. I took all my dive equipment to Lynne's house agreed to the the sale conditions and left with a good feeling that all would be sold. Some of the items were sold and payment was made to my account. When it came to my regulator, this took a while longer but eventually received confirmation via mail that the regulator was sold and that Lynne would make payment that same evening or first thing the next day. That was the last i heard from Lynne. I have sent numerous mails, left uncountable messages on her phone. with no luck. this was the beginning of September. There is still a hole lot of equipment that i have with her. I did send emails that i wanted to fetch the unsold equipment but not heard a word. She does send monthly updates to Friends of mine so i know she is still operating her business (I don't receive these mails anymore). I can only advise anyone looking for a dive operator to be careful when deciding to deal with Dive locker.
