Receiving threatening smses of being handed over for debt collection with NO prior notice of outstanding ammounts. Last statement received last week has no outstanding amounts???? As if this is not a ridiculous expense already!!!

Received an sms informing me of outstanding amounts owing (no info regarding any outstanding amounts stipulated) - I was not once phoned, emailed, smsed or informed in any manner of any outstanding amounts owed - last statement dated 2018/01/30 has no outstanding balances... Is there not any process of communications before handing your clients over to debt collection services informing them of outstanding amounts???? As it is I am one of very few people paying towards this ****ty service - now I get threatening sms'es - tried calling the call center - do not have time to waste on waiting for *** services in excess of 10mins... I want to know what I owe and why am I owing if there is a agreement to debit my Credit card with the fees?? If your systems are not working as intended - DO NOT MAKE IT MY F****ING PROBLEM... I WANT A CALL INFORMING ME WHAT IS OWING, WHY IT IS OWING AND WHY I WAS NOT CONTACTED PRIOR TO RECEIVING **** SMS'ES FOR WHAT IS OBVIOUSLY SERVICE FAILURE ON YOUR SIDE!!
