Unprofessional and unhelpful staff at @Home Canal Walk

@Home Canal Walk. Staff were extremely unprofessional. They tried to tell me I could not exchange a defective cutlery set that I had purchased the day before (it contained 7 forks and 1 table s****, instead of 4 forks and 4 table s****s). After checking with the manager, the staff member told me that I could not exchange it because then they would sit with stock that they cannot sell. After putting up a fuss with the manager, Farah (who claimed to not know what was going on even though they had been discussing it in the back for 5 minutes), all of a sudden it was fine to exchange. They asked the @Home Living space store to bring over a new set. After waiting 30 minutes with no update, I told them to just credit the set. There was no apology for the wait. Also, the staff members shout to each other across the store to help customers. Extremely unprofessional.
