My Bills Not working

I have tried now for two months to pay my PAYE through the My Bills Function and it doesn't work. All goes fine on the Efilling side and when I log into my internet banking to release the payment it tells me my bill cannot be found. Calling the call centre is useless as they don't seem to know the system or how it works so they cannot advise me. They inform me they have regular problems with the SARS Efilling and I should add them as a beneficiary and do a manual payment. This does not resolve the issue that the My Bills function doesn't work. Doing a manual payment means SARS takes longer to allocate the payment their side which creates more hassles for me as I now have to call SARS for a reference to make payment. Why can they not ensure their My Bills system works.
