I clicked on the link to esso in the online visa offers website & used their garage finder to see which local esso supplier was closest & open. Spent £45 on fuel & waited... & waited. It was only after a week & a half I looked back & saw its limited to 'participating garages', and there's a 'finder' on the visa offers esso webpage, doh !
I'm also wondering who & how posters above me emailed complaints about failed offer purchases as I can find no contact details on the visa offers website.

This says it expires tomorrow on mine.

But I used the Costa deal last month in a costa franchise and it still gave me the cashback no problem

Be wary, I've had a 75% failure rate with these offers, some track, other don't.
Oh and don't expect any help from HSBC on this, their customer services don't even have a clue about this promotion.

I'm still waiting for the Boots £5 cashback via HSBC from 2 weeks ago. After several emails from utterly useless hsbc online customer services, I've escalated, but alas still no reply.

Still chasing them for a Lidl £10 - unreliable tracking system and hopeless to deal with.

I had to chase them for the tenner from Lidl purchase, they then paid out after a few days. Worth doing.

Lidl and Curry's last week worked, saved almost £40

used this on Lidl offer and received £10 within week.

Same and I didn't even buy any fuel

Went to an esso station with a Tesco express, because the bill went against Tesco (I only bought petrol) I didn't get the fiver.

Not on mine. Probably account specific. I had this offer a few weeks ago

Used this last month on the same offer. Had to email them to get them to refund the fiver but it got there eventually. Possibly a one off mess up by them.
