Elderly Parent Paying over £55 a month

[Jacol75]

Hello my mum who is 82 went into the EE shop as her phone wasn’t working properly.  She now has a new phone, contract, tablet and insurance totalling circa £55 per month.  
She only really uses the phone for messages and calls when she is out and about (although uses WhatsApp more for messaging), a bus tracker and a few apps/games.  She also now has 25gb which I believe is too much as her usage will not be this much per month.

I don’t believe this is the best contract and she didn’t fully understand what she was signing up to.

How does she go about canceling this and starting again to get her something that more suits her needs and affordability as it has only been 10 days since she visited the shop.

Ordinarily there is no 14day automatic right of cancellation for anything purchased in an EE shop - the statutory right of cooling-off only applies to sales & contracts concluded via distance-methods, i.e. by phone or online.

Your recourse will therefore be by returning to the EE retail shop in question and complaining of what you allege is mis-selling. The formal complaints route is another option - https://ee.co.uk/help/contact-ee/complaint
