TELKOM USELESS VERY FRUSTRATING

I have 3 contracts with telkom, first one derbits from Nedbank on the 20th ,2nd one derbits on Capitec on the 30th but they just changed from Capitec to Nedbank on their own. Fortunately there were enough funds.I let them continue by making sure there were enough funds always until end October when they decided not to derbit. After that they charged me for non-payment of which it was their fault I even submitted bank statements as proof thereof but still they continued to close both my lines even though I paid the whole amount except the R202 for non-payment and I've made it clear that I won't pay it because there were funds they didn't derbit I paid R888×2 for October and November just not the R202

TELKOM PLEASE OPEN MY LINES
