The worst client service from Netstar

The experience that I've had is atrocious. I contacted Netstar on behalf of my husband. I was told I can't access his account because I don't have authorisation to do it. So we did it in writing by email. From my husband personal email. This was done on the 14th January 2020. No reply to anything. We don't know what we paying for. We don't get Statements. We just need answers but Netstar just ignores....
