All of the Lifestyle Home Appliances staff I dealt with, including those on the phone & the two young delivery men, were excellent. All were very friendly, cheery, polite, efficient & professional. All communication (emails, phone calls & tracking) from Lifestyle Home Appliances was excellent.
My order arrived well within the time window indicated, and it was in good shape.
