Online store a little cumbersome when it comes to shipping and delivering orders with Biogen

I placed an order last week 25 Mar online with Biogen, first off there was no stock avail and I was told they would process my order once avail and then secondly I get a message yesterday with the courier saying they tried to place the order and not sure where to go. Come on guys I ordered stock last month and didnt have this issue, sort out your stock levels and courier issues, right now its easier for me to just drive to Dischem and buy that way and if thats the case why have an online store in the first place?
