Groupon has been repeatedly calling and emailing us about advertising. We can recall at least 3 months of calls and emails, maybe more. We told them months ago we do not want to advertise with them. They continually call and tie up the phone lines, we are a medical office with patients who cannot get through when they are calling after we asked them not to- we have a list of multiple patients who have had to leave messages when they call because Groupon will not stop talking and the staff has been intimidated. (I have since advised them to just hang up). Today, 070819, "Angello Bray" from Groupon called and I asked him to take us off of their call list and stop emailing us and he fully denied that request. I told him that we do not want to do business with Groupon. He proceeded to tell me that "If you don't want any more customers than you are sad" and he continued with several more insults. I asked for a supervisor and he refused. I asked for the department that would handle complaints and he refused. I asked for a return phone number for Groupon and he refused. After I hung up the phone he emailed us, after I advised that we dont want any more phone calls or emails.
