Paid for data that I did not receive

I bought data for my account and it was instantly used I tried this 4 times(even though the connection was turned off (The data could not be used)) I afterwards contacted the support through their client on the website 3 times and was basically told irrelevant information and dismissed for example (\Your 1gig account does not receive after hours data") and then I would reply and explain that is not the problem but would receive the same type of response. After that I decided to go to their live chat. The person I talked to saw the problem but could not fix it and told me he would contact his supervisor and get back. He never got back to me. The day after I decided to call the contact center. I talked to someone and he also saw the problem and said he will go to his supervisor and get back(spoiler alert) he never did even after he said at most it would take 1 hour maybe a little more. I then called again and got hanged up on after telling the problem. Then I called again and was told they see the problem and can see the data was never used but they will not refund me since they say it was probable my fault their system was not working. I strongly recommend using another ISP. """
