Delivery of item is over and above Hyperli's responsbility

I ordered a shoe cabinet on the 23 November 2018 on Hyperli.com. Delivery was estimated between 3-5 working days. On the 26 November 2018, I realised that the delivery address autofill incorrectly filled in Durban as the city instead of Johannesburg. I sent an email and Monique rep**** stating that the order was already on its way to Durban and would have to be re-routed which would delay delivery - I had no problem with this. Two weeks later, still no delivery, I enquired with Monique and she responded stating that she thought that my order had already been delivered. A week later and still no delivery, upon enquiring with Monique, I was told that "we've been liaising and trying to get this sorted with the Couriers and is going over and above what is required" So apparently Hyperli's job is to receive payment and whether or not you receive your order is not their problem. I was then given the courier's details and told to contact them myself. The courier then informed me that they had not received the item from Hyperli and therefore couldnt deliver. After several more phone-calls to Bex couriers delivery was arranged for the 18 Dec 2018 - the delivery was not received. I called again on the 19 December and was promised that the parcel would be delivered on the 19 between 13h00-15h30 - again the parcel was not delivered. I sent an email to Hyperli with this update and no response has been received to date. I called Bex couriers again this morning and was once again told that they have not received the parcel from Hyperli - so what exactly was supposed to have been delivered on the 18 and 19 December. I'm not sure whether the problem lies with Hyperli or Bex couriers, either way, there's no communication, nobody gets back to you and Hyperli doesnt have a call centre which means that if they dont respond to your email, then there's nothing that can be done. This was my first experience with Hyperli and I definitely will not be buying anything from them in future.
