Tax certificate misery

I needed tax certificates for my current and savings account. I went to the branch (Cresta) late in June and was told they were not available yet. A week later I returned and I was told they were still not available and I should try next week. I did come back and they were available, but was told the system was slow and they couldn't provide me with them. Subsequently. I was sent an email which contained the tax certificate, but this certificate made no reference my savings account. Went to the branch again, but after waiting 20 minutes for service, I could not continue a s I had to return to work.
