Denny's Antenna Service

I first had dealings with Denny's Antenna Service in late when I chose to install their Stacker antenna in my attic, with excellent resultsAt that time I did not need or make much use of their services, and I only needed to repeat one of my few emails before receiving a response
About one year later, my situation was quite different, and so was my experience with Denny's customer serviceIt started when I attempted to get advice via their antenna recommendation serviceThere was no response to a number of enquiries using their online form, nor to two emails requesting assistanceEventually, I took the risk and ordered the same Stacker antenna I had used a year beforeThe package was lost by UPS and resulted in the only responses from Denny's over the past three-plus monthsThey shipped a replacement without issue
Since this antenna was to be installed on the roof, I placed a number of orders spaced over about six weeksEach was shipped promptlyDuring this time and shortly after receiving my current order, I received an unexpected notice from USPS indicating I had a package comingAfter verifying through the Tyvek envelope that it was as a duplicate of my order, I marked it as such for return to senderThough I called within Denny's office hours, their voice mail only gave the office hours before cutting off the callI notified them the same day via their online contact form of the duplicate order being returnedNeedless to say, within minutes of USPS confirming that it was delivered to them, UPS notified me it was on its way back to me
A subsequent request using their online contact form on April to ask for advice concerning reception of a troublesome station remains unanswered a week later
Denny's HD Stacker antenna has worked well for me on both occasionsTheir prices are mostly reasonable and they ship promptly, but I would not rely on them for pre- or post-sales advice or guidance with product selection or usage
