Avoid at all costs! Their customer service is beyond terrible, in 15 years of having credit accounts I've never had an issue and in 8 months with M and S bank I've had 3 major issues. They are also incredibly cryptic with their payment dates to trick you into getting missed payment charges - my statement was dated January 27th and said my next due date was Feb 19th. I paid on Jan 27th, the second I read the statement. To my surprise I have a missed payment charge, customer service say "oh the statement is issued on the 27th so you have to pay on the 28th onwards for the next statement". I've never know a bank issue statements that request money on a date that falls within the previous month's payment window. They also didn't refund me fully when one order arrived with items missing, so they essentially stole money from me too.
