Telkom is harrasing me

We are been harrassed by Telkom network. I got a call from telkom selling me a phone contract which i accepted, they delivered a phone without a contract, method payment it was debit. so now 1st month they debited and 2nd month they said debit went though and came back but they dont know why, i was told that the day i went to menlyn telkom store,so i went and pay manual at pick and pay month amount of R189. so after i have been receiving non stop sms I must pay R202 and i called they said it was because the debit didnt go through ,which is something that no one explained to me so i spoke to Qiniso Phokasi she said I must pay R391.70 i told her why because the debit issue it was not my fault money was there on my account. yesteday i went to menlyn mall telkom again and they requested a callback. consultant called Tebogo called me around 17:07 and he said now I must pay R593 because of the debit for this month again, i told him this month i payed at Pick and pay on the 31st may R189. service was unhelpful and i said how much should i pay today for my account to be upto date, he said R202. I need to payup and close this nonsense of a contract.today i got sms that you are sending me to you attornets. i am also going to open a case regarding this, see you in court and I will also go on media, you are harrasing me and you always unclear on what you say.
