MRP Home has no idea what they are doing ...

Not really the way I like to do things - but i’ve sent more than 30 e-mails and i’ve spent more than 2 hours all together (more than 15 minutes every time) waiting on Mr Price / MRP MRP Home / Mr Price Home to answer their phones to help with an issue which they seem unable to do . I ordered a piece of furniture - when it got delivered - it was the wrong item - waited 3 weeks for a replacement and recieved it - wrong item again - the same one they originally delivered - this was because their item codes were incorrect (not my fault) - i needed this item quite desperately so requested a return for the wrong one again - and decided to be refunded and re order another shelf (the original one was now out of stock cause it had taken so long) so i paid again (R350 delivery again as well) and recieved the new one a few days later - the item came unassembled - with 15+ parts and zippy bags full of *****s - but no instructions . I have now been querying for a week to get some instructions sent to me - as well as my original delivery fee and the first order to be refunded . They have double the money that the item cost and two delivery fees from me and I still do not have a usable bedside table ! I’m out of ideas and options and not sure what to do . I’ve spoken to 4 different customer service representatives and they have thus far not helped . Hopefully they’ll see this ...
