"Terrible customer service"

My husband and myself booked Flu vaccines via the Lloyds Pharmacy portal - place and time confirmed by email. When we arrived the pharmacist was unaware of booking. When a member of staff advised him why we were there he said "What about it" and glared. His response was rude and dismissive. After checking his computer he said he would do it out of "courtesy" but had no vaccine . No apology no offer of alternative date either.
