We agreed that they'd take their money on 15th of every month. One month they didn't so they debited me twice the month end. They then sent me SMSs every day saying I'm owing them. When I enquired they said everything is fine and they have decided to change my debit order to be end of the month. Now they debited me on July 29 for August. August 8 they sent an SMS confirming payment, 15th August they tried to debit me again. I disputed the order now they saying I'm owing them and they stop my services. When I phone the pinetown branch which is always useless when I have a query, they told me to phone 081 180 which doesn't take me anywhere. Pinetown staff doesn't know anything they'd tell you to phone back after a certain time or just direct you to 081 180 where you will follow prompt that does not lead you to speak to a consultant.
