Had similar last month:
Nespresso Coffee has reported an updated transaction price of £5,298.77, for which you collect 13,212 Avios for your order.
As a result, the original 74 Avios you collected were removed and another 13,212 were added to your account as “pending”, which will be approved and credited within 24 hours.
I never received promised 13,212 Avios, though my spent was less than 1% of the quoted amount, so never chased it either
