Rip-off and requesting back payments which doesn't belong to them and have no idea how previous account from previous Body Corporate were handled

I am an owner of Brenton Hill since July 2008 to date. When I moved in we were under CSTM body corporate which was later removed in July 2015 because of mismanagement of funds and all their documents were confiscated. All was good and my levies payments were done accordingly till they were removed. Brenton Hill then appointed Primo as per their contract attached and their contract which started from December 2015. To my surprise I received their statements dated from 2011 with low brought forward amount - see attached (not knowing where were they in 2011) and claiming to date I now owe them R19k and sent me summons as attached and emails to say they want to repossess some of my house contents, as you can see my proof of payments calculating from the time their started and backward, I have always paid my levies in advance, our levies were R540 per month but I would either pay between R800 - R2000 per month which was more than our actual levies but all my payments are now backdated to months which were paid to CSTM and I am asking myself why is Primo claiming unknown amounts on behalf of CSTM i.e. from 2011 whereas they have been in existence from December 2015 and my payments have been again way above my initial levies with them.

I went to Pretoria Magistrate court Pretoria 2/11/2017 since I have been advised by legal advisor to respond within 10 days to respond to their summons which I received this past Saturday 28 October 2017 to check if they can assist to reverse their decision because it Is unfair to me and they feel powerful over me especially or have the right to confiscate my stuff when I have my proofs of payment for the term they have been there and paid way over the amount claimed as per documents attached. I will appreciate your soonest response since I won't have access to my emails outside Rand Water premises. It will surely be unfair for my furniture’s to be pounded whereas I have paid and just because they have powers and have summons with no side of my story? And my proofs of payment attached.
