I've Tweeted, reTweeted, Twitter DM, FB DM and I have received no response Ever from Sainsbury's. I gave up reTweeting & DMing asking how can I tell I get priority grocery delivery slots. I'm not giving up on this though, 10000 Nectar points spent on my Sainsbury's online grocery shop 25th October. We have realised that the points have been deducted from Nectar card/account but this is not showing on Sainsburys receipt, points/money was not deducted from our bill. Sainsburys contacted by phone who advised contact Nectar, fail to understand why when the points were not deducted at checkout but have disappeared from Nectar account. Nectar investigating for us who have since advised no reply from Sainsburys and it can take can take up to 28 days for Sainsburys to respond. Shameful.
