Account debited when no phone line or wifi

My phone line and wifi did not get repaired for the entire month of February. Finally after getting the number of someone who would actually listen, my phone was repaired after 4 weeks of chasing. Telkom then had the audacity to debit my account. I have spoken to them on the phone, twitter and Facebook and all they say is tgey will get back to me.but again, 4 weeks later and nothing. I want my account credited. I will not accept paying for a product that did not work for a month!!!
