What a **** service provider , i was billed twice for an upgrade and they say it’s cause I did not cancell the other plan where else they did not explain or notify that we supposed to cancel after an upgrade . They added more extra speed without my go ahead and charged me for it. The agents don’t wanna escalate my issue future and they drop my calls . Furthermore, apparently they don’t share the ‘recorded’ sales calls to clients. So how will we prove what we agreed on ? If good service is what you want, stay away from Rain
