Telkom (Finrite)

I paid Telkom finish in June 2019 after having a 2 year contract with them. I went into two of they're stores and one was offline Telkom (Vincent park, East london) and the other one Telkom (Hemingways mall)i did not get proper help because i didn't want an upgrade i just wanted to get away from Telkom. I even phoned their customer care call centre. Everything was paid up but then I heard i still owe them money after phoning Telkom and Finrite.I paid it up no one told me i have to call the insurance company to terminate my contract with them too because I thought everything goes together meaning(if I close my account that has been paid up with Telkom that goes for the insurance company"finrite" too) but surely it was not like that. I use to get my statements through the post but later found out i owe the insurance company(Finrite). I contacted them and they told me to pay the outstanding amount that was in August but i paid it after 2days after month end, when the next month came i found out i had to pay them again and they said i should have paid them before the new month so now I have to pay another instalment and they add interest too and now it's December and Telkom took a R682.86 on 30 November 2019. On the 06 December 2019 I phoned Telkom and Finrite because I received an invoice stating i still owe them R1125.64 (that is interest they say i owe for late payment) these guys don't even phone they just take your money from your account and doesn't even care after getting money from you for 2yrs straight they still want to suck you dry...#Hellopeter please help! I can't afford to pay that money!
