No Notification of change to Zimbra

I suddenly saw ZIMBRA Client when accessing my e-mail last week. I had no idea what had happened.<br> I thought it was a virus and alerted our technical dept, which was embarassing and a waste of resources.<br> <br> I could NOT click on LINKS to verify a subscription.<br> WHY WAS I NOT INFORMED OF THIS CHANGE ???<br> <br> I have been a MWEB client for many years and expected an e-mail or SMS at least.<br> I almost lost a contract because i could not access information via a link sent to me in an email.<br> <br> What is Mweb going to do to compensate me? <br> Even if changes are meant to improve customer service or experience, it should be communicated BUT i cannot get to a web page by clicking on a link, even if i press CTRL or ALT.
