LACK OF SERVICE

I am so utterly disappointed with the services in June I received an SMS & email to update banking details as their is a payment owed to me. I submitted 6 documents 6 times, called numerous times, went into the branch on 28 August, all information was updated on the system, 29th resubmitted again ..and once again documents failed!!! This is so frustrating now, my 7th attempt online. Still no agent or anyone at SARS can help me.
