I ordered six bottles of wine with my grocery order, taking advantage of the 25% off six bottles offer. On the day of delivery two bottles of the same wine were out of stock.
The two unavailable bottles were substituted for just one different bottle of wine! This meant I lost the discount and had less wine.
I complained to customer services and did not get a response for nine days.
After chasing I got a very dismissive response saying I no longer qualified for the offer as I only received five bottles.
The customer service representative was dismissive, bordering on rude. No explanation as to why the picker would substitute two bottles for just one and no apology for the inconvenience. She refused to escalate my complaint to a manager and told me to return the wine to store if I wasn't happy.
Am I being unreasonable to be very cross?
I expected more from Sainsburys for some reason and has left a bad taste in my mouth than cannot be washed away due to a lack of wine
I cannot go to store. I get online shopping due to disability.
