Quick to take Money. No delivery of goods. Weeks to process refunds. Insane refund policy for online ordes

I ordered a number of goods online for delivery. I received one of the goods whilst the rest were never delivered. I was not informed that the items will not arrive together in the same delivery, I got a shock when only one item arrived. I had to phone their call centre more than 10 times to find out what was going on with the items. After several repeated confirmations of my contact and delivery details, I had to finally accept that they actually just do not care, I asked to be refunded for the items that I never received. I was told that I cannot be refunded until the goods are returned to their warehouse by their courier, something that had nothing to do with me was then a dependent on me obtaining my refund. I'm not sure why their courier does not confirm if goods can be delivered before they accepted my cash, but now when it is time to return my cash, their courier is a factor. This was a two week long process and till today I do not have my refund because nobody is keeping me in the loop, nobody is telling if the good are returned and that my refund is being processed, in fact, I was told two weeks ago that the refund was processed and it take 5 - 7 working days but I still have not received my refund. I don't know how many times I had to call the contact centre since emails do not get responses for weeks on end.
