No help from ABSA Internet Banking Help Line

My free Trend Micro anti virus expired on the 1st of April. Since then I have tried several times to renew my subscription. I have the correct serial no. The download takes well over one hour. But just when the installation is complete- 98%- I get an error message. Trend gives 5 steps to get over this message but even after this the installation stops at 98% with the same error.<br> I tried to get help from the ABSA Internet help desk and got nowhere: 1st call I got given another tel no which turned out to be the ABSA credit card department who in return put me back to the Internet banking helpline. This time I was given another tel no which turned out to be the service helpline for Trend Anti virus. There I was told that ABSA contracted out of their service and that they are now fully responsible for any technical problems.<br> I decided to contact my local ABSA branch on 7-4-2016. The ladies there were very sympathetic and tried their best to help but the best they could do was to advise that I might get a call back as soon as the consultant from the helpline got supervisor permission to phone me, as they are not allowed call back without permission. Up to today I have had no contact
