Standard Bank Insurance double standards

I had a revolving credit account with credit cover prior to increasing the amount a few days ago in branch at Langebaan. I noticed that my credit cover was removed and queried this. However after the lady assisting me phoned the relevant department whom informed her that credit cover is up to age seventy. I was given a letter to sign reinstating credit cover. However after receiving the contract at branch the following day I noticed that credit was excluded. I again queried this at the branch and numerous telephone calls to standard bank but still I was not assisted. The money was paid into my account notwithstanding my dissatisfaction with the understanding that it would be corrected. Two days on and few telephone calls to standard bank today still no resolve. It would appear that there exists a lack of training as policy differs from branch to branch at standard bank
