Worst service and cancels orders without consent

I tried to order a birthday gift online on 9 March 2019 to be delivered on 12 March 2019. First I could not succeed to the payment option on the website - it kept on saying technical error and I must call into the call center, which I did and they only said I should try again tomorrow. I did try again the next day with the same issue. I finally managed to get through to the payment option and when I did it said "payment failed" even though it shows on my side it went through. When I tried to sort out the problem the call center was of NO help at all. Everyone said they will investigate and get back to you but I have not had any feedback since I brought the situation to their attention. After sending them all the proof of payments and them trying to find now a missing order and payment as well, they decide to cancel my order completely??? Not only is the gift late now there is NO gift at all.... When you try to call in to ask what the hell is going on they either don't answer or they are sooo rude. When I made it clear I never canceled the order they only reply sorry they cant help me...

How is that for customer service?!

If I never order from them again it will be to soon..
