Worst company ever

Good day My name is mirriam and I soo regret taking out a contract with telkom They dont debit from my account on the last day than they end up saying that my account is arrears. I always leave money in my account for them to debit I've sent them my bank statements but they still haven't assisted me and now they keep adding a penalty fee of R290 for failed debit I'm soo frustrated and regret ever taking out a contract with them...and there customer service consultants are very unprofessional and dont know how to speak to there clients I spoke to kamugelo on the 4 December she was rude and did not want me to speak to her team leader...
