Envelopes are always out of stock

I've just been to the Post Office in Mount Frere and for the second time this month they do not have any envelopes, I was there earlier this month and they had no FastMail envelopes so I had to drive to Kokstad to buy an envelope. They do not even have the envelopes for ordinary mail and the gentleman at the teller had no clue when they would have envelopes again. This is saddening because when you go to Post Office branches in towns where there are also white people you experience a better service and this is sadly my second complaint about the Post Office in Mount Frere.
