Ongoing issue with failed transactions

Over the past 6 weeks, I've been experiencing a problem whereby my payment is regarded as failing on Takealot's side, however the funds are reserved for Takealot on my bank account.<br> <br> The issue has recurred twice this morning, and I have begun engagement with Takealot.<br> However, I am extremely unhappy that we cannot get direct access to someone from the payments department.<br> I have my private bankers ready and willing to assist, however I need Takealot to be forthcoming and do their best to resolve my issue. I am not by any means a casual customer of Takealot, and have spent tens of thousands of Rands at their store, so I expect some dedication from them.<br> <br> Please provide me with a single point of contact (not a call taker) to resolve this issue in collaboration with my private banker.<br> Online transactions on Groupon have never failed, and therefore I believe that this is a Takealot issue.
