Poor Service

I've submitted my returns from last week monday the 06/07/2015 after 08:00am and have been taken to pillar to post without any luck.Was told my acount was handed for investigation and was requested to submit more documents because im changing my banking details and i did that and i still dont have my money. On e consultant adviced me that i'm only short banking details and all will be paid into my account i should not worry about the investigation process and its been done already and i took another day off just to sort this out and it's still not sorted. Today i called the call centre since it's the only way to communicate with them and spoke to Nicki Sigxaxhe (supervisor) and she's telling me my case is still pending investigation and it shows that my previous banking details still exits on the system and if money was to be paid into my account it will go into that account as it was neverr removed when i submitted the new banking details. I want my funds to go into my nedbank account and i dont have time to do this anymore and i need these funds immediately and dont understand what's keeping me under investigation for so long. Can you please ask these people to help me?Thanks
