Caller: Telechoice

Telechoice called me from this number, I know it was them because they left me a voicemail message.
(Not a spam call, was in response to an issue i was having)

I have been receiving calls from this number 'TC Overseas Help' (02) 8069 2938. It looks like an unreliable number. TeleChoice normally communicates via email, so I don't pick up these annoying calls.

Caller ID said 'TC Overseas Help'.
No message was left

I didn't answer and they didn't leave a message. Name on my phone said 'OTC Communications'.

Caller: I don’t know

Pretending to be Telechoice I called Telechoice they said hang up but at end of call go it could be us we have a call centre in the Phillipines. The msg I was left was hello then hung up. Not professional at all.

Caller: Telechoice

Telechoice chasing money owned by an alleged breach of a 12month contract - which I did not, it was a month to month contract as shown in my portal. I've got a screen shot too!!!
They keep leaving messages but static only.

I called back number (02) 8069 2638 rang once then goes to busy tone.
