Assupol telecommunications gone wrong

I requested a call this morning to request for a tax certificate. For some unwarranted reason the person I spoke to change my email address by incorrectly spelling. The call had nothing to do with the me changing my details. At this point I can’t change it on the portal by myself hence I’m still waiting for the tax certificate, honestly I have sent emails requesting for this certificate countless of times without help. I called your client service line and had to hold for over 2 hours honestly there’s no level of this treatment that can be considered as acceptable. At the beginning of the tax season all parties initiate sending tax certificates to their clients but never your company one must run in circles trying to get one.
