just to link my number so i can use internet n cel

I cannot believe the level of service im getting from nedbank. it is indeed very disappointing. opened my account online October 2014.card to me at home and the account activated. once that was done, then it became a nightmare to use it. my internet profile was set up and the bank sending notifications to my old number that was used when I was a student even though I provided my new number. I have been to the branch 4 times already to sort this out and its still not done, today I went,continuously calling the branch and the call Centre to get this sorted and still no response, im told someone will call me and that is not done. I cannot transact via internet or cellphone banking, I cannot go que in the branch everytime for even small things.is there any bank that really takes its clients serious. please recommend. I cannot believe they cannot sort out this small issue, how pathetic.
