Based on the available information, it appears that the caller with the number +64226519849 is likely conducting a survey or research of some sort, as they sent a link that was supposed to be opened by the recipient. However, the link did not work, prompting the recipient to call back, only to be met with no response. This suggests that the caller may be using automated systems to send out links and may not have a team available to respond to follow-up calls. The lack of a functioning link and unresponsive follow-up calls may indicate a lack of legitimacy or professionalism on the part of the caller.
The survey link sent failed to open; a follow‑up call to the same number received no response.
