Not doing as promised

My provident fund paperwork was received by Old Mutual on the 13/4/2014 whereby I was told that it is in process and they are just validating my bank and SARS clearance. I phone again to find out how far they are with the payment just get be told they do not have my ID or marriage certificate (as my bank and ID is not the same surname), I told them that it was handed in with all the paperwork, but e-mailed the the copies again. I phoned again and was told they received the e-mail and will carry on with the process. Phoned again to find out what is happening they told me it is ready for payment and I will receive the payment on Friday 08/05/2014. Monday I phoned again just to hear that they have taken my file out of process as THEY did not attach the bank validation forms, but my money will be paid within 3 days. After a long argument they escalated the problem, but I am still in the dark as to when the money will be paid out and receiving feedback from them is non existing. I had to phone again this morning to just hear the same thing. WE WILL CONTACT YOU. Feel like charging them for all the phone calls and bank fees that is now going sky high. SOMEONE PLEASE HELP !!!
