Boss Auto Spares rib me off

I order parts online, paid full amount of R4500 plus delivery amount R243.30 for an E90 Control Arm Kit on the 26th of November, the website specifies 2 to 7 days delivery, I was hoping for 2 to 4 days when I order seeing that they are located in Johannesburg, Maraisburg and I in Pretoria.

On the 06th of December, 11-days later I called, now frustrated, gave them my order number #***, I was transferred to Online Sale, no answer, after a few attempts the phone was answered by an energetic brother, very polite, by the name Norman, took my order made hold while he checks, came back to tell me, "Sir we had a little problem putting this kit together but you order will be sent out today, I will make sure of it."

Two days later on the Thursday 08th of December, I had to call again and sent through to Online Sales several times before the phone is answered, when eventually someone answers, it is still Norman, he even remembers my order as soon as I gave him the order number, he tells "this order was supposed to be out already, I remember this one, you see Sir I write down everything. Let me check something out and call you right back, this order will go out today. Can I call you back on this number?" he asked, we had an agreement that he can call me back on that same number.

13th of December, still no delivery, no call from Norman, I am ****ed, furious and frustrated calling Boss Auto Spares, being put through to Online Sales where no one is answering my calls anymore. I now sure that the confirmation of my phone numbers was just to my number to the "do not answer" pile.

I think Boss Auto Spares just ****** me, they ribbed me off of R4743.30, meanwhile my car is still unstable on the roads.
