Poor Customer Service!!!

So I wrote a review on Rain Internet service provider earlier this week I got a reply shortly after I posted my review that a rain agent would be in contact with me. So it’s been 3 business days later and I still have not heard anything back from rain!!! Help me understand how it is possible for the support staff of rain not to give a damn about customers that are having issues with there product or service??? I mean you are a telecommunications company if I’m not mistaken. So how is it possible that you guys can not communicate with customers???
