Highly Frustrated!!!

Hi Old Mutual I would like to know how you guys operate? I am trying to get a hold of you guys the number *** for the past few weeks and every single time I hold on the line over 20 minutes and end up cutting the call because nobody answers. I have sent NUMEROUS emails and I receive a response after 2 weeks at a time. I understand that we are in Covid times, but most businesses should be back to work so I don't get what the delay is, its very frustrating to have such a small query go back and forth, I received an sms with a ref as me to call you guys and yet again , I hold on with no joy! THIS IS NOT A FREE NUMBER AND MY AIRTIME IS BEING USED! Please contact me on the number provided, I want this sorted out ASAP!!!!
