We have 2 investments that's expiring

We have 2 investments that's expiring. One on my daughter, the other on my wife's name. I have power of attorney on both. Nedbank called me but was unable to help me, despite the fact that I have power of attorney. I tried the last 2 days to contact Nedbank Brackenfell to give notice, and make an appointment, but I'm transferred to a call center that's completely useless. Can someone from the branch please get back to me, so that I can give instructions, and make an appointment to reinvest. I NEVER have these issues with Absa, and I already took over R 1,000 000 to Absa due to poor service from Nedbank in the past. There isn't really a lot of investments left at Nedbank. Unless this is what they are trying to achieve?
