PnP online spend - check you get the right Vitality points!!

I bought several items from PnP online and received tax invoices for both spend. The invoices clearly indicate with a giant "V", which items were eligible for vitality points. I noticed though at the end of the month, I didn't receive the full correct allocation of points and raised a query with the Vitality team. * 5 weeks later... * 10 emails later * 3 submissions of the actual tax invoices noting the vitality points, a full explanation of why I believed I should have been awarded more points (toilet paper and other household cleaning products were not "naughty" items and I wouldn't have had points deducted from the claim) * 4 different Vitality team members replying * 1 letter stating my query wasn't valid * 1 letter asking for details on the spend (someone obviously couldn't scroll down to page 2 of the attachment) * 1 letter stating my query was valid and the problem of missing points had been resolved * 1 escalation email from me 2 weeks ago asking someone to call me * 1 very quiet phone whilst no one actually calls me Very disappointing service from Vitality - I expected better and more competent people (actually, once a query is logged, only one person should handle it, too many cooks in the kitchen messed it up!) to contact me, and at the very least explain that if I'm wrong, why my maths is wrong.
