Opened and billed for two accounts instead of one

I subscribed to the Telkom LTE internet option for R500 per month in March this year at Wonderpark Mall. The process took long and in the midst of my application the power went off. I was asked to come back the following day to complete the application, which I did. I paid the deposit plus R500 rand in cash at the registration and debit order of R500 from my account each month. I had service for only one month when my account was suspended due to \lack of payment". I called 10210 from my cell phone"
