Bad customer service!!!

I have bought a R70 000 water purification system and asked The courierguy Polokwane branch to pick it up. It arrived with a broken pipe at my doorstep. The installer of the water purification system tried to fix the system, but failed. I asked the Courierguy to pick it up on their cost and return to the place of purchase, but they refuse and they insist that the unit was not broken when it was at the Polokwane branch. They also confirmed that they did not remove the bubble wrap to check if there were anything broken on the unit, prior to sending it of. Ryno, the manager at The courierguy Polokwane states that it is clear bubble wrap and he could investigate through several layer of bubble wrap that and found nothing broken at the Polokwane branch. There is no way to see through even one layer of the bubble wrap. there were about 4 or 5 layer! I have tried resolving this with Ryno, but he does not reply to my messages and he does not answer the phone. I added his number on a group i created with the supplier i bought from and then he eventually rep**** and stated that the parcel was not broken at the Polokwane hub, now he escalated to the Joburg hub to see if it was broken there??? How can it be broken there, fixed at Polokwane and broken again when it arrive at my premises??? Very bad service and no attempt to resolve this issue at all, from The courierguy side...
