Discovery Vitality withhold deposit - *******ly according to CPA

So there was a glitch with my activation of shoe booster, and although activated, I was not aware and never used it, Vitality can prove they sent me an email, which I subsequently found in spam folder, on asking for activation I was told their rules are clear and my deposit is forfeited.

So they can prove the mail was sent and rather than accepting customer error and helping me correct they see me as at fault and keep my deposit.

**** of vitality says it's my fault and deposit is non-refundable, despite my CPA rights being raised, that says it is ******* to withhold a deposit, saying they won't set a precedent

Now I can live with them expiring my smoothy and points or any reward they give me, but my cash is a little dearer to my heart, which makes me very frustrated, it is simple you cancel deal you refund the deposit , not abnormal business ethics unless you are discovery, where they have numbers, not customers.

So do I try to take Discovery to court over a small amount ? or just cxl my subscription, it costs 4000 a year to subscribe which I don't believe I get the value for, so I am tempted to just cancel Vitality and get my money back in savings in that I pay more than I benefit.

I suggest you do the same cost worth exercise you will be surprised at the lack of value and imagine the peace of not having to jump throuhgh hoops.
