Not having a good 24hrs in HK

Went out with Peter and Heather and Ewan (mop boy) on the rip the other night. Of all the people on the tour they were by far the coolest to just hang out with. Especially mop boy. was so sad saying goodbye yesterday. it too hard. Wanted to sneak away but it wasn't possible. Good luck guys and it was a pleasure.
Things turned a bit sinister last night. For the last couple of weeks I've been getting a lot of missed calls on my phone, especially when i get up in the mornings. I check my email regularly so I know that it's nothing to do with family etc. It's not like i have to worry about work. So I thought maybe my mortgage has bounced or my credit card company needs me but I checked all of those. So last night I was lying in bed, it was late and I was watching tv and my phone rang, this man on the other end asked to speak to Dave, I said sorry wrong number and hung up, he rang back, "Una I need to speak with you why are you out of the country, I need you ...I love your sexy voice ..." I hung up. He rang back, i diverted, he rang back, I diverted, he rang back, I answered, "I said stop calling me I am away from home and this is an emergency number only ..." I threathened to call his network and have him barred, he kept calling about 25 times, I couldn't sleep. And then it stopped .... until this afternooon at 4.30 when it started all over again. I called vodafone and they said they could do nothing for me ... i can't believe that. It's very upsetting especially on the cusp of the first part of the trip where I am on my own again. Whoever this creep is I hope he gets ebola and dies a long and painful death.
