FYI to folks here who plan to return their Samsung products due to change of mind or warranty purpose.
I decided to return one phone because I purchased two so they told me to email their infamous estorenz team, waited two days with no results so I called their 0800726786 number and they told me they will escalate this with the estorenz team so I'm at the waiting stage.
I believe their 0800726786 and estorenz are outsources to the Philippines who in turn is handled by https://transcom.com/ a Swedish outsourcing company which provides customer care, sales, technical support.
Read their google reviews here https://www.google.com/search?q=samsung+nz&client=firefox-b&… and be prepared to fight for your CGA……

I'm pretty sure the CGA doesn't apply for change of mind, only for products that either don't match their description, or are faulty.
