I am sorry this has been your experience.
I have shopped with the Q 30 plus years. I have never had to wait more than five minutes for a representative. Now they will offer a call back that takes no more than five minutes.
They continue to be helpful whenever I have questions. I just called them, because I did not receive a confirmation on a return delivered to UPS but labeled to US post office. It was confusing. She found it and gave me the credit.
The times have certainly changed for all customer services across the board. I have so far had good luck with the Q.
