Shocking service and broken promises

The power cord to my router needed to be replaced. Keep in mind I have no Internet for as long as the router doesn't work. I called Rain every singe day for the last week and a half to get that done. Ever agent says they will call back but not one has. Every day I'm told the next day it will be delivered but never comes. That is times a agent didn't call back and a cable didn't deliver. 6 times! I spoke to a team leader Ricardo who said he'd call back. Also didn't. Sent an email saying tomorrow. Next day I reply to his email to follow up he is on leave. I have never had such terrible service from such a verity of people from the same company. It is not worth the savings on Internet as I have had to in the last two weeks load data on my phone to compensate for the lack of WiFi at home. This has already cost me more than the months premium at rain. What's the point of having to pay for bad service.
