SLOW RESPONSE

Last week Thursday round about 07:00 I app**** for an online layby on Sleepmaster's website and I received an email saying that someone from their call centre will call me within 7days so that I can make a payment.I never received any call from them,so I called their call center on Monday and I got a reference saying that someone will call me and no one called.I called them AGAIN yesterday and they said someone will call me by the end of the day.AND NO ONE DID! I really love their beds,but their slow service is disappointing me cos I'm going to end chowing my money that I saved up.I don't have time to go to their shops cos of my hectic working hours and the online option is convenient for me.
