Horrible service

Day light ******* from Rain I upgraded to the new router that's when my trouble began. I am now getting a dounle billing and they are refusing to cancel the old router. My debit order date is the 15 of every month but without my authorization it was changed to the 1st of every mother. The net***is bad every day each time I ask for network I am told to swith off the router and nothing is done at all. I. Am struggling to meet ends meet financially because of this world double debit. The law should assist us where to report such painful cases
