Unauthorized debit order

In the 23 of February an unauthorized debit order of R429 went of my account from loan connector with ref Lconnector ********** 550161 so I reserved and stopped the debit order because I never enteref into any agreement with them..and on the 18 my husband gets an email from loan connectors stating that I'm in a bridge of contract with them as I haven't paid for the service the y provided from the 24 January.. My question is what package have they signed me for as I never called or spoke to anyone from tbier company regarding any services and where did the get my detail from as this is ***** going to someones account without their permission.. Better yet where is the supposed contract to prove I took any product from them as I am not even sure what they offer... I'll be taking this to the ombudsman. I am a very angry consumer and I so hope to Got this doesn't affect my credit profile.
