Worst Service from FINCHOICE

Only reason they are getting one star is because there is no option for 0 stars!Worst service from all ends!I requested a settlement amount and I payed it about a week back,and up till today they are still asking me fro proof of payment I followed all the steps and did everything that was asked of me ,they don't accept bank statement,they don't accept screen shot and even when I sent a PDF as they requested they saying they don't accept this as well,this is horrible service when we don't pay they quick to hand us over for payment but when we request a settlement amount they can't find the proof of payment which was done a week ago this is very annoying and will be taken further as I have followed all steps and this auto mated message is just a waste of time.i will never use this service again!If you don't accept any of these proof of payments how the hell do I send a proof of payment!?
