Dear Petros,
We are sorry you have been disappointed by the outcome of your claim.
Unfortunately it is Sainsbury's Grocery’s policy that they do not accept claims on missing claim as stated clearly in their purchase condition. Therefore, we are unable to investigate your missing transaction further due to the fact that the retailer does not accept claims.
We’re sorry we could not offer further assistance regarding this matter.
For future reference, we suggest you:
• Clear all your cookies before you log into your British Airways Avios eStore account next time so that when you click out to the retailer only the cookies created for that purchase is recorded.
• Do not go off to other websites before you complete your transaction (including direct to site, search engine, Google ads, banners, email/newsletter, coupon sites, other reward program etc.) as interrupting the browser session that started from British Airways Avios eStore can affect tracking and overwrite the last referral as being from us.
• Temporarily disable any ads block software/extension when browsing our online mall.
• You may try to make your purchases on other devices and browsers to see if this makes a difference. When doing so you are advised to first test and view your click from your Click History that located under "My Account" at the top menu at
http://www.shopping.ba.com/, so to make sure the setting of the new device/browser being used is all good.
Thanks again for contacting us.
