Non compliance and customer not being kept informed

I app**** for a home loan with standard bank,provided them with all my recent information according to the fica regulation,I have been communicating with them all along with no problems but once the loan was approved the bank called me on a number I have not been using for years,then because the bank couldn't get hold of me on the number I did not provide the application was closed.I called the complaint department which took time to resolve my complain but eventually did manage to re-instate the loan.Then the loan was handed over to the lawyers to finalize which took more time,Then I asked for their lawyers to make amendments on my application which I never received feedback about when I called the bank to find out if the amendments where done I was told the application is closed and cancelled.This has caused so much emotional stress and financial stress.They dont call to give clients feedback I always have to call them to request feedback,This is not acceptable and clients are not valued at this organisation.
