Faulty Merchandise/ TERRIBLE Customer Service

I have been a loyal Groupon customer for many years. <br> <br> I recently purchased an instant Gazebo, which I used for my birthday just under 2 weeks ago. I used the gazebo, and when closed it after use, a component failed, causing the gazebo to break, I contacted Groupon the next day, who asked me to log the return via their online platform. I did this, only to receive an email the next day stating the the return request had failed. I contacted the call centre where \Carl\", emailed me asking me for collection information. This info was sent through, 2 days prior to me confirming collection. I emailed Carl the next day, asking for confirmation, to which he never rep****. The following week, I called customer care line again, where Kirby assured me that she will resolve my query. She emailed me the very same form. I have still not received a response. I called customer services a short while ago. I asked \"Chadwick\" to put me through his superior, as this absolutely ridiculous! As I type this complaint ,I have now been on hold for 18 minutes. I will now be voicing my complaint ,through all forms for social media. <br> <br> You will be losing a faithful customer Groupon. Shame on you. "
