Delay to deliver on time-ebucks shop

Last week (24/05/19)I purchased something using my e-buck with the hope it will be delivered early the following week. I could not be able to track it on ebucks track my order, it only reflect the activity that was done on the 25/05/19 when it was dispatched to the courier.

I called ebucks shop on the 30th to find out if there is problem,the issue was escalated to found out what could be the problem. Today (31/05/19) I got the feedback that the courier company could not reach me during the week,however no sms or voicemail delivered on my phone to validate that. I'm told that the order will be delivered Monday(03/06/2019) and I have to accept that.

I must say that I'm not pleased with this kind of service I have received from the ebuck shop together with the courier company (dawn wing), and the untrue statement about not being available on the phone.
