Billing

Pre Ordered the Note 9 on the 9th of August online. Sales agent called me to comfirm all details. My first debit went out on the 14th of August. I received my phone on the 27th of August. My first bill came on the 1st of September, was charged pro data and 1 months normal bill. But my first debit order was not reflecting. I called Telkom, spoke to Dineo she said it will reflect on my second bill. I have now received my swcond bill, and the first debit order is still not showing. I called billing today - they said I need to call sales - called sales, they put me through to billing, and once again billing says call sales yet I have been on the phone with them for more than an hour and noone is helping me only saying call another department, and Im from one department to the next. This is UNACCEPTABLE! I want my money back!
