Poor Service under staffed

I went into the Postnet at Benmore and asked them to bind 3 large documents.<br> I left the documents with them and said i would return in a half hour to collect<br> On return the job had not been completed and the staff member who served me was serving other people<br> When asked why she didnt complete my job she said they were understaffed and she just helped other customers<br> <br> The manager was called and was unhelpful<br> Eventually another 20 minutes later the job got done<br>
