Incorrect delivery not corrected after 2 weeks

I ordered a corner couch unit, two piece, online, Friday 8 May. The 14th the delivery team arrived and off-loaded, but, it was two of the same pieces, this unit has two different pieces. The delivery company contacted Mr Price and they assured me the delivery will be corrected ASAP - note the delivery company, not Mr Price. Only after I contacted Mr Price did they provide any feedback. The following Wednesday the delivery company called to schedule a delivery, but no-one came. I called them to query and they were shocked, Mr Price was suppose to contact me to inform me that they once again botched the order (same mistake twice). Again, I had to make contact with Mr Price to get feedback. I am still waiting for my correct delivery. I have escalated the query at Mr Price, yesterday afternoon. I am still waiting for feedback. The customer service from Mr Price has been lacking in the worst degree. The order should be checked at the factory, not once off-loaded, where is the correct protocol? Something that was suppose to be a fast and convenient transaction has turned to something sour and beyond inconvenient.
