Sarcastic Service

I have ordered several times from Planet54.com from last year. Always happy with customer service, delivery and quality of products. However, ordered a parcel on Sunday, saw on confirmation e-mail that delivery can take up to 15 days. This did not suite my delivery deadlines so called customer service to make alternate arrangements. The lady on the other side was very accommodating and assured that she will dispatch my parcel to arrive before the end of the week. Today, as the tracking service on their website is down, I e-mailed ********** to get a status of my parcel and I get the most sarcastic, unhelpful responses from "Nathaniel". After giving me a vague response to my status; "We deliver nationwide in South Africa and the delivery period is 7 working days from receipt of order confirmation". This is not the answer I was looking for, so I explained my encounter with customer service telephonically on Monday. I get the following response; "Wow that is awesome. Well if she said it You can believe it." - I do not appreciate this sarcasm, but rather expect helpful service. Planet 54, you are a great platform, please ensure the faces of your company adhere to your standards. I still have not gotten a status of my order, and do not have time to engage in e-mailing all day to get a direct, simple result. Thank you.
