Total scam. Ghulam will offer you discount n you will lose all your money. They will reverse all the transactions they make on your bills. They are not even based in Australia. They will offer to make payments on your utility, tax, loans etc & will offer you discount. & they will use stolen credit cards, once they make these fake payments, they will ask you to deposit funds in different bank accounts and after few days all transactions will be reversed. Don't get in this trap.

Caller: Ghulam-E-Murtaza (Sales & Finance Executive)

They call you on WhatsApp and pretend to be based in Australia (actually they are Pakistanis) who bought virtual Australian mobile number and offer you to pay your Cellphone, Electricity, Gas, Water, Tv, Insurance, Fines, Tax, Land rates, Invoices, Medical fees, School fees, College fee, Mortgage, Car loan, Personal loan etc. and claim to give you 30% - 50% discount on all bills. Once they make the payment ( which will in fact reflect in your utility account ), they will ask you to bank transfer discounted amount to an unknown bank account. In my case, bank accounts were in name of R P Raj (Suncorp bank), Vidhan Chandra Verma (Westpac) and Jaydeep Bhattacharya (Bankwest). Once you transfer the money, they will raise a dispute with the utility company and all the payments they have made will get dishonoured after a month or more. Dont fall in this trap as are hardcore bastard scammers and I have dealt with many of them and lost $4200. These are their fake mobile numbers I have identified so far but there could be many more:
