Shocking Customer Service and Still No Delivery of Paid Appliance

Ordered a washing machine online on 31st May with a promised delivery of 3-5 days. It is 12th June and still no delivery. I have called repeatedly and promised every time that someone is looking it, someone will call back and even guaranteed delivery before 5pm. No-one takes ownership, no customer service manager will call back and not one piece of accurate information or an apology anywhere. Possibly the worst customer service I have experienced in this country. Requested a refund in order to process with another supplier and still nothing. They don't even respond to emails. Unbelievable and unacceptable. Do not ever use this company.
