RETRENCHED - Teljoy refusing ANY payment arrangement

I have been retrenched from end November 2018. I have called Teljoy in December 2018 to try and arrange a different set of scheduled payments. They however said it cannot be done. I have also asked them for settlement amount to settle all my accounts and they said also this cannot be done. Today (18 June 2019) I phoned to ask them for payment arrangements as I still have no income an am receiving UIF on this month end. I have made a payment on 3 June 2019 and am still R1164.44 behind. I'm capable of paying this account in full on June month end.

I have been a customer now for about 5 years and have had no hiccups at all, now they don't want to assist me until end of June 2019??
