WireIT website not secure

Every time I try to log in on the WireIT website to review my history of prepair electricity I get the following message: Your connection is not private Attackers might be trying to ***** your information from www.wireit.co.za (for example, passwords, messages, or credit cards).

I telephoned their customer service number and was told that there is "probably a problem with the server".

It seems as if there has been a "problem with the server" for the last 2 months.

Unacceptable!
