Connection failure when calling contact center

<p>I have made numerous attempts to contact Computershare contact center and every time the call gets disconnected after 3-4 minutes. I attempted again this morning but with no success. A moment later I called again and the automated voice operator advised to call back later due to high call volumes. There are other reputable companies with a call back system if that is the case, why can a company like Sanlam/Computershare not incorporate this system as well? Your success lies in your automation processes, or lack there of in this instance.</p> <p> </p> <p>I would like feedback ASAP, thank you.</p>
