Count me as someone who dreads the customer calls.
More times than not (much more), they are excruciatingly awkward. The sob stories, medical issues, all the "one more question" as the host desperately wants to end the call, painful non-dialogue because as the caller is watching on TV they forget that nodding their head cannot be heard through the phone.
On rare occasions they are sweet and/or funny. But more often they just seem like time fillers so the producers can catch up with tallying sales numbers.
Those calls are such a relic of the past. In the 15+ years I have watched QVC, I have never been persuaded to buy from a testimonial call. In fact, I have turned the channel frequently.
QVC claims they are undergoing changes this year. I hope getting rid of the testimonial call-in line is one of them.
