Bad account service

On 04/04/2015 I contacted FinChoice and requested my settlement amount this was e-mailed to me R5650.70 by M.Harris, I made an EFT payment and faxed and e-mail ed the proof their of to [Email Removed] and [Email Removed] on 07/04/2015. I phoned to confirm the receipt on the proof. I was told they did not receive it. Ever since I've sent proof 18 times yet they asked for my detailed bank statements I don't like sending statement but, I did. On 04/05/2015 I phoned them and asked if they would please refund the payment deducted for the month of May R1611.07 wrongfully as the account was settled in full. I was informed that the refund will occur within 24-48hrs. Today 06/05/2015 I phone and inquired regarding my refund and was informed that this will not happen as I did not put my I.D number as reference and that I now need a letter from my bank stating that this amount was in fact by myself and that the money was paid into FinChoice.''s account.<br> Please please help me as I now can not afford my medical aid payment due to the payment they refuse to stop from my account.<br>
