I called tech support for the 3rd time with the issues. This time the issues of freezing and channels going black for an extended period of time was happening. the CSR sees I have been having issues before and wants to schedule a service call to"see if the cables or wiring are bad." Well, they cant do after 3pm calls and I am NOT waiting here on the weekend. My tie is too valuable with family as I works 6 days a week. I pleated WHY when the cabling is fine and its does it upstairs on downstairs. My HR34 has been flawless in the family room, but when I move the Hr21 there, its has the dame issue. So its NOT the "wiring." So plead with to change in results. I said goodbye to the CSR and figured I would try something else. rap like this is WHY I hate DIRECTV. Same issue the first time I called with the old DVR. 5 tries and finally got a CSR who sent out a replacement. I have the PP and this is only the 3rd time since 2000 I ever had a DVR go bad. So I call back and say cancel. I explained my frustration and issue with the HR21 to that CSR. 3 mins later she gets a new DVR out and I thank her. So we chit chat about football and offered me the ST for 1 year for free as a loyalty gift. I told them to keep it, as honestly, i can't reap the benefits of it. But thanked her. I said 10 years ago before kids, hell yeah! She asked me what i think of DIRECTV, my service and pricing. i said I was overall happy when I get service like this. I did mention bill gettign high and I know in part, its due to the fees form the networks. But happy in general.Shen then offered me 20 off my bill for 2 years as a thank you! it was an immediate credit as I payed my bill today and it was $20 cheaper. This was unexpected and I wanted was a damn new DVR. Times like this, is why I love DIRECTV and what I expect form a good company at times for loyalty when your loyal. So lets see how the new DVR works out.
