Telkom is ******** me

End of August 2017, i took a contract (24 months) 20gig for R 200 pm from Telkom. i couldn't pay the first month which resulted me paying doubled by the end of the following month(Oct) = R496. they told me if a debit bounces they charge me R 299 per transition. so after i was expecting to go back to normal R 200 debit, which they did not debit end of October, ended up billing me R 598.94 end of November. following that i decided to make manual transaction only to found out i wrote incorrect ref number for both payments, called telkom was told not to worry i just need to send proof of payment that money will compensate for the following months to pay i have not gotten any feed back regarding that matter. previous month(February) telkom debit me R598 which i do not know how it got to that amount, after that two days ago new invoice comes through indicating that the above R 598 was not paid meanwhile they did debit it as a result i have to pay R800 this month adding the monthly instalment. my biggest problem with telkom they debit any day they feel even after i told them to debit on the 25th. the consequences of debiting any day is the R 299 they charge me for it bouncing back. i am on a 6th month with this contract which mean thus far i should have paid about ( R 200 x 6 + 299 {first month bounce})= 1700 but i have paid R 23O1.99 to this point. please help me resolve this issue. i want them to do the right thing a debit me on a same day monthly in that way there will be no consequences of confusion.
