Trudon taking your money without any signed contract

I started working at a new job almost 3 weeks ago and my employer asked me to look into the Telkom account regarding an entry made to her account every month for R696.00 with description "Web 2050 Info3 IYP" with reference number ***. Can someone from Trudon please contact me on *** so that we can discuss the fact that no contract has ever been signed between my employer's business and Trudon.
