Thanks for your post @priyesh123
I'm sorry to see you haven't heard about your cashback. From what I can see we emailed you on 29-Sep-2020 00:01 and as the offer wasn't claimed, it expired on 29-Nov-2020 in line with our cashback terms and conditions Here.
Having said that, looking at your correspondence with us via Twitter, as you got back to us with your account details 1 day before the cashback offer expired but we didn't get back in touch with you in a timely fashion, which meant that we couldn't provide a direct link for you to claim your cashback before the offer expired, I've raised this to our billing team so we can send out a cheque to you as an alternative resolution instead.
Also I'd love to honour this by sending a reward card rather than a cheque however we've no way of manually issuing a reward card because the claim form in the email we sent has expired so I hope the cheque helps. I'll provide an update within the next 5 working days via your account.
From 31st October 2022, I no longer have a regular presence here as I’ve moved on to a new role.
