You have lost a loyal customer - and now I want my money back!

I bought 2 Mother’s Day ‘instant vouchers’ on the 4th of May. My money was taken but the voucher numbers were never sent to me nor my mothers.... so no Mother’s Day gifts! I have literally tried to follow up on Facebook, Twitter, call centre, email- you name it. Have reference numbers and my payment ref and have not heard a word back. I am absolutely livid! I am insulted that your supposed turn around is 72 hours and think the apology email from your ceo is a joke! It’s been over 2 weeks. I want my money back. I can no longer deal with this level of incompetence. I am done!
