Bad and no Service.

There is no way of getting help from Sars, their lines are faulty or no one is available, voice prompts only use is to inform that no service is available to call later, then when calling later, high call volumes call later, there is no service from SARS, I can't even book a branch visit and the self-help option don't cater for my query. I need to upload more than 20 documents and can't due to the maximum being 20. I have been calling SARS for a week none stop several times a day. How do they expect one to submit audit docs on time with this bad service? can someone please get back to me?
