I have a cordless V7 that is under guaruntee until 26th November. The battery seems to need replacing - a conclusion I’ve come to after following all the trouble shooting procedures and then online chat. The online assistant told me last week it would get back to me about a new battery and so far heard nothing. If my machine is still under warranty, how do I go about getting replacement parts confirmed? I’ve tried phoning the help centre but have been told my wait time is 103 minutes! I don’t want my guarantee to expire before this has been resolved.
