So in May 2014, we were given a HTC M8 due to signing of a contract, by Vodafone. 

It developed a fault, handled under warranty by Fonefix in Auckland. It was entirely replaced with a new device then.

It developed a second fault (well known stuck power button issue) this week. 

VF are saying only the original warranty applies. 

Fonefix are stating they only warranty 90 days or until the original warranty applies, whichever is less. 

It is a business device, purchased under a business name. 

It feels poor that a device that has such a well known issue wouldn't be covered under warranty for this. 

Do I have recourse?
