Bad service, bad security

I have been a happy client of Afrihost for the last six years. However, a recent accident with a mobile data product of theirs has made me question both my loyalty to Afrihost and their integrity. Yesterday, 6GB of data vanished from this product. I thought it may have been my mistake, such as a computer update (even though it is set as a metered connection) or hack as the MiFi device was active the whole time. So I change the password of the device and recharge with another 6GB. This time, however, I switch off the MiFi device, deciding only to use as necessary. This morning by 11:00 all of the data has been used!!!

I got into contact with Afriost this morning, talking to a consultant named Frank, who spoke to his manager. I got informed that Afrihost does not accept disputes on mobile data, but that I should download a program called GlasWire which will track exact data usage. However, GlassWire cannot track historical data, and it is of no use for my problem.

I want to know: what is going on at Afrihost? Is this internal cloning of my sim card? I did not give my sim card to anyone. Can I not dispute about R500 usage of data when my MiFi device is not even on? Bad service, bad security.
