Feeling very frustrated with Bluebean

I made a payment on the 19th April 2015 on my Bluebean card. On several occasions I have been speaking to different customer service consultants regarding my missing payments, they all requested me to send through proof of payment which I did. The first proof of payment I sent through was on the 07 May 2015, thereafter I sent it to 3 different consultants and up till today I am still waiting on someone to let me know what happened to my payment. It's very frustrating and time consuming for me to call every time and explain myself over and over and no one can find my missing payment. I dealt with a manager as well on one occasion and she never had the decency to call me back. I am really not impress with the service I have received from Bluebean and I hope they can sort out my problem as soon as possible. NB. This is not the first time it is happening to me:-((
