Oh, man you really had a bad experience. You really need to complain to DISH about your experience with THAT retailer. With enough complaints, they may shut that guy down or reduce their status. I don't see any faults with you since you did the prep work and all and made the installation doable and simple enough as a standard professional installation. But as you can see, the culprit is in the delivery where the dispatcher didn't relay the right info. about a bad LNBF and a shoddy install. As far as calls and appointments go, that can be understood as I myself am a retailer and sometimes can't call a customer back. But if and when DISH Support calls us, they don't tell us to call the customer back in 30 min. If I say that we're busy and we'll call later today, they'll simply say "Oh, ok, that's fine."
But all in all, you got stuck with a bad install and bad taste for sure. Just don't recommend that retailer to your friends and/or call that retailer directly and express your woes. Sometimes, a trouble call is a trouble call and the crucial details are lost in translation. I've already complained and suggested to Retailer Services on better info. when they give us trouble calls. The notes that are left on the customer accounts are sometimes incorrect and incomprehensible.
