i do not answer 02 83 very annoying

I missed a call from this number. When I went to call it back (20 mins later) I received a message saying the number was disconnected? How can someone phone me from a disconnected number? I'm baffled

Numerous missed calls from this number as early as 7.30am - as late as 10pm. No voice messages. Rang the number and engaged on several occasions. I can only assume - call centre/telemarketing?

Forex & Bitcoin scam. They ring at Stupid O'Clock at Night.
The general gist of the call is to get you salivating about the gains to be had by trading LEVERAGED Forex & Bitcoin, get you to open an account, chuck some money in, and because it's leveraged, you can lose 100 times the amount you lose in your trade. So if you lose $300 in a bad Forex trade, you can owe up to 100 times the $300.
You can also make Gains that are 100x leveraged too. So you are essentially placing a bet that a commodity will gain or lose value, you can bet on it either way since you are never buying shares in the company, you are just betting on it's price changing.
Stay away........

I called back number (02) 8379 2361 rang 3 times then goes to busy tone.
