On 10 February 2017, I have a credit enquiry on my credit report from Optus Financial Services NSW. I am not an Optus customer, and would like the enquiry deleted as I have not made any enquiry/purchase of Optus products in the past 4 years. I have spoken to approximately 10 Optus operators already and they all can't find anything on their system and keep on transferring the call to another department (sales, customer service, Optus financial, chat manager) How can I go about this? Thanks.
FWIW the occassional credit request on a report has little to no effect on your credit score. In fact having or requesting credit can actually increase your score as it indicates you are engaged and in control of the process. You can probably safely leave it to eventually drop off.
Possibly someone tried to get a free phone by submitting your details but that hasn't worked.
Regardless its best to get the credit agency to remove the entry, not Optus:
