Samsung - Phone delay and no communication

My cellphone order was due for delivery last week Wednesday (13th) , however I requested a change of colour on Sunday (10th)which impacted the delivery date. I phoned on Wednesday (13th) to find out when I can expect the phone to be delivered given the change in order. Customer service said they would phone back but didn't. Thursday last week I phoned again, they again said they would phone back but didn't. I then emailed Friday last week, they apologized and said for the third time they'd get back to me but didn't. I then phoned this morning (Wednesday, 20th) and they said there was a delay with the courier company, and Samsung asked the company to contact me. It it now the evening of the 20th, and I still have no idea when I can expect the phone to be delivered. So not only am I still waiting for the phone, but there is no communication from Samsung or the courier company. This is extremely frustrating. If it's not delivered tomorrow then it's a long weekend and at least 13 days from when the phone was meant to be delivered.
