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……
Just my 2 cents, I previously had a support ticket via estorenz and honestly they went above and beyond for my query. The guy I dealt with ended up sending me a small gift item as an apology. So like all place YMMV.
