poor customer response

I sent through my claims form with liberty life on the 5th of may and two days later I did a follow up with the form and the lady I spoke with told me that everything was fine exept that my form wasn't signed and no stamp from my previous employer...I then sent the form to my employer then got the form to be signed then again I called to check if the form was received and luckily it was but there was another problem again the form ddint have a date of withdrawal of which the lady who I spoke to initially told mi that...the problem was only the stamp and the signature...my question is what's next?what is the probability that my form will be correct this time around and why is it that liberty doesn't inform its customer in time incases of errors done.
