Bad costumer service from RSAWEB

So far I am really unhappy, they have deducted 2 months of wifi costs. I work for a very small salary as I am still a student. Tried phoning them but no answer, I send emails with no reply. I have opened a ticket that has been closed without anyone helping me to get the extra months cost back. I also tried online but no one answers me. Today I send a whats app and was promised to get an email response that still has not happened.

RSAWEB also deducted 3 months of wifi costs from my aunt this month. Don't know if anyone else has had this problem before. Just be careful
