Not Happy

I have called The Courier Guy at least 4 times since Monday, and all times I have been told that there was a mix up/issue with my delivery and that it is sent back to the warehouse but will be delivered immediately (this is Monday all the way until today- still same issue). My patience is running quite thing because everyone from the call centre keeps lying to me. The warehouse is in Germiston, I live in Kempton Park. My son needs these textbooks for school, can you please sort this out ASAP!
