Urgent compensation for non compliance according to policy

Good day I had placed my hisense 32inch TV at cash crusaders Lansdowne corner Cape Town I was paying my extensions with no hassle for the past 4 months I received an sms on the 22 November to say that payment was due I immediately called the shop no answer I tried consecutively from the 23 November there were times there was no answer and on 2 occasions when they did answer the man that answered said there was something wrong with the computer and I needed to call back I woul wait a few minutes and call back my airtime was running out and I was becoming frustrated eventually on the Monday the 25 November I called again when the lady told me my TV expired I did not make an effort to call so it is now sold I became so emotional a d cried over whilst explaining to her that I have been calling ever since I received the sms later on the Monday afternoon I called again to speak to the manager I was told the manager was off by the name Mikael, I spoke to the current manager on duty Priscilla explained exactly what happened she promised to give me a call back I was never called back . I have a printout of the call log from my phone with all the times I have called. Cash crusaders you went against your extension policy as well as poor customer service I would like to be compensated for this you obviously sold my TV for triple the amount you loan to me.
