Poor service

I purchased a DSTV decoder which comes with installation and it was delivered yesterday. Today I called DSTV and they referred me to Makro and they referred me back to Dstv. Now I'm told that I need to request an installation voucher that will be used by the accredited installer. I called the call centre and they told me to call the store. Why offer a service that you can't even provide help nor guidance when its needed
