Disappointed

I ordered with these people on the 15 December and I'm still awaiting my order Every single day they telling me they will have to reschedule my order. i have cancelled my holiday simply for this order. The last person I spoke to today was Olga she suggested me to cancel and they will refund. How can u tell your customer that instead of telling me she will handle the matter. The courier service when u track online they say they couldn't deliver. They cannot say it's because they didn't get me at my address because I've been at home. Both Mr delivery and superbalist 've was despicable. I'm still waiting for my order.
