Debt collector for telstra they are a company called charter mercentile
Have been calling all hours of the day.

Same here. I'm definitely not an Optus customer, so there's no need whatsoever for them to be calling me.

Caller: ‭(07) 3620 7580‬

We have no outstanding debts so this must be a scam.

They always seem over eager to get me to give our bank account details over the phone even though i have told them iwill not do that. Sick of there lack of english skills and excuses.

Well they keep ringing us & we are not now & ever have been with OPTUS so all I can say is its a SCAM

sick and tired of them calling at all hours...phone me during business hours and I may answer but call me before 8am and forget it...have spoken to them and made arrangements but still keep phoning and can never understand the person on the other end.

nothing but pressure you can call up to 4 or 5 times a week and always before 8am and have even had them call at 9pm ...can never understand them as their english is very bad and they are very rude

They are the debt collection agency for Optus. I was put through to them after calling Optus direct. They do accept Bpay although they obviously try to pressure you for full payment via credit card or direct debit. I have received paperwork from them in the mail too.

Rubbish! They cannot make you pay with credit card over the phone. Don't fall for it. HANG UP.

Rings before 8am!!!

Debt collection agency.

It is infact the debt collecting company for Optus, they do sen out multiple letters, and try to call many times, they are legit and if ignored can lead to a court summons, in order to pay much much more!

Does anyone know who this number that keeps calling me is?

same happened to me! I don't even have account with OPTUS!

I think it's these people:  http://www.chartermerc.com.au/

they called me last week saying i owed optus 180 but the account isnt in my name and i gave them my home address before realising. i called optus today and we owe them NO money at all and optus doesnt have there number in there dept contacts so yes it is a freakin scam and and im pissed!!

We have had the same, we believe it is a scam, nothing they say add up. I don't believe they are from the above company, even though they suggest they are.Saying that we owe Optus money and to pay it right then and there via credit card, no option for bpay etc. and no evidence via a letter in the mail.
