Bad Customer Service

Good day My brother has been trying to get information about our late mothers shares that she has purchased some where around 2009. we had had the worst service as we do not expect that we be the ones to contact yeboyethu so many times just so that they give us information on these shares. we also do not know were her dividends have been going if she has been receiving any and if she has been has the money been growing or what has been happening. all we want to know is what happened to the shares so that we can be able to close all our mothers assets. My brothers number is ***(Senzo Sithole) ***/***
