Frustratated by lack of communication

I started my claim process with Alexander Forbes on the 30th of April 2015. Everything was submitted on my behalf by my previous company. I waited and waited, calling in each day to find out about the progress of my claim. In this time I was not told about any documents that needed to be submitted in order to get my pay out. Then on the day that they decided to pay me they sent me a text saying they tried depositing my money and it was rejected by the bank due to a bank validation process that failed. I had to send in my signed bank statement and certified copy of my ID. I am so frustrated and wish they could have maybe asked for these documents at the beginning of the process so as not to take up more time than they have already taken. Now I have to wait an additional 5 days to get pay out. simply ridiculous...
