I have been a client of Rain for sometime now and at this moment I'm very frustrated with them. Since Sunday, 30th March, I have NO CONNECTION...after several calls I'm still without WiFi service. I paid my subscription for the month of April and I had WiFi for less than 2 days. No one calls you back or email you, to follow up on your inquiry. I just had Connection for less than an hour now and again I'm back to NO CONNECTION. This is really no right what rain is doing.
