Horrible AI customer service

How about you stop using AI nonsense to handle your customer care?? I have been trying to cancel my Rain wifi since the start of the month and if I want to use the option to cancel it via the website, they are requesting return of the device within 7 days if I return it to a store or 5 days if they must collect it, but in the same sentence it says that my service will be available until the end of my current billing period which is the end of the month. Make it make sense? I tried contacting them via phone and was on hold for what felt like a lifetime and eventually requested a call back. Someone then called me, but the line on their side was so bad that I could only make out that I was speaking with a female and nothing else, the more I repeated that I could not hear a single thing she is saying, the more she tried to speak. I eventually told her that she would have to call me back and then put the phone down. Surprise, I have not yet received a single call back. I have tried to get their AI bot to log a call for me a few times and even though it says the call had been logged, to this day I have not yet received a call. This is becoming a problem as I want this cancelled, but as I paid for the full month, I am not willing to have the device collected before the end of the month.
