Nothing works for me.

First of all my internet banking does not work. If I go to the branch to get it sorted it works for a day or two then it tells me that I have already logged into the app. As a result I am completely unable to do online purchases. Secondly I have been attempting to open a tax free call investment acc. Whenever I do it on the app it tells me that it has failed I must contact the branch. Last week I called the branch and no one seem to be able to help me. Was sent from pillar to post with no assistance until I ran out of airtime. Yesterday I called again and spoke to a very helpful gentleman who made me go through about 30 mins process with him. I did so until he told me that the system requires him to escalate the matter and he would call back once all is in order. I waited for the call and eventually he called back but we could not hear one another. I thought he was going to call again and he did not. Up till now I do not have a tax free acc opened and activated. I do have money to save and I do not have money to buy more airtime to call again. I have spent a lot in airtime trying to get all this sorted.
