Yesterday I got a massage from rain that my account due end of January 2024, which really surprised me because it is not supposed to be that way because I am not behind with payment to be reminded.from that moment I started experiencing network problems, especially in the afternoon. I managed to call them today and they picked up call and gave me instructions to follow and so far so good.
