Customer Service? What customer service????

Had absolutely no issues the entire time i used their service even referred them to multiple staff members,friends and family, but then I moved out of my apartment at the end of Feb, tried to move the service initially, that didnt work, tried to cancel the service with Vox since February the 2nd 2023. Sent MULTIPLE EMAILS, MADE MULTIPLE CALLS THAT GO UNANSWERED. Currently on hold with them for 22minutes for the 3rd call of the day. Just got hold of someone who said she will call me back in 1 minute since her internet was down....hmmm "Telecom service" Can someone possibly let me know how to contact your offices for a resolution on this matter...Or do you only focus on new business?
