No feedback and Poor service all together

I have been given the runaround by the fund for weeks now and every time I call in to find our what the delay is I am requested to submit the same information, yesterday I received and sms that my payment was rejected due to a bank validation and later in the evening receive an email hat the payment was successful and will reflect in 3 day, when I call this morning I was told my details are not in order and I need to submit the same information AGAIN, fortunately the lady that assistemd me was able to put on her thinking cap and go through their records to find the documents and resend these to their back office, now I have to wait another 5 days for something that sjould have been sorted without me having to call in again, I am utterly disappointed in your service and the run around and trying to manage me has reached its end. I need urgent assistance on this payout and for the back office or whoever is not doing their job and get their act together. This is so beneath you,47 for a company that has been in service for so long to treat clients like this?
