Very poor service

i took a J7 phone for R299 and had a contract for R199 which i later decided to cancel as i was not given a phone when i claimed. The insurance company (Finrite) had cancelled my insurance as per request but telkom is still debiting me. i contacted telkom on 081 180 and spoke to a lady who confirmed that they can see a debit that occured and that will still take place in the coming debit date has no change. she then said i need to call the insurance to cancel it,which i did way before i even contacted telkom. I asked the insurance company to send me a proof of cancellation which they did. they further confirmed that they dont deal with insurance per customer,they just do admin and claims. i dont know what to do, i sent an email to ********** which lwazi responded and said i need to call 081 180 he just taking me back to level 1. my number is **********
