A month to resolve a case and being charged for 2 LTE accounts

<p>I app**** for the Smartbroadband uncapped Wireless 3 on the 13 July. They contacted me and i told the lady i am upgrading my existing SmartInternet 15gb+15gb contract as it says i am allowed to in the terms and conditions on the website. On the 8th Aug i received my invoice and both contracts were active and I was going to be charged for both of them. I contact them that day and informed them that it was supposed to be an upgrade, not a new contract and was given a case number. I called again on 17 Aug and they put a note on the system for someone to action the case. I was also promised that someone would contact me, which never happened. I called again on 22 Aug and explained the urgency that they were going to be over-debiting my account because they had not done the upgrade as requested. I was told that they would be investigating further and i received a sms on the 26 Aug to say the case had been closed. On the 1 Sep they debited my account for both of the accounts which i was trying to avoid. I called them on 1 Sep to find out why the case had been closed and why i had still been debited for both accounts and was promised that someone would be calling me - which still to this day has not happened. Are you going to wait until the end of Sep to over debit my account again? </p>
