Poor business

Frustrated after spending a total of 6hours and 27 minutes over 4 phone calls and still my issue isn’t resolved. Technical department says I should call cancellation department and they say no sorry you need to speak to support, after about 10 email tickets logged over the past 3 months with an automated response “help is on the way” to say your ticket has been logged and we will get back to you…. No one ever got back to me. Now it came to a point where my business phone number has no service and not one of the 3 *********** service “agents” could help me and all said we will let you know before end of business and yet again got disappointed. Sitting with a number which I used for years and they (Rain) as my service provider can’t help me.
