Bolt Unfair Practise

My son has been recently been blocked from using Bolt. When he made a follow up he was told there has been irregular activities. He's a university student and as far as he knows he's not aware of any activity that happened in his account. When he requests further details he's told that they cannot divulge the details due to their privacy policy, Earlier he was told that there was a ******* with no details. They then changed the story to say there were irregular activities. I now need to give him money to book uber which is much more expensive. What they are doing is very unfair to him as a user. I'm going to take this issue to the media cause Bolt does not want to give him more information. The person who communicated this is Deslin from Bolt Customer Support
