Pain in the bum!

Got the second email asking for a review/feedback from super e-cig today and the feckin parcel hasn't even turned up yet, never mind try out the products! So, my review? I hate companies that beg for praise and they only get to do it once. I won't use them again after. So, guess what? I won't be shopping at super e-cig again. Still appreciate my feedback? Nah, didn't think so.

Hi, Sorry that you have yet to recieve your items as it is still within the window for delivery I will need to wait to reaise this issue with Royal Mail. Appologies for you recieving 2 feedback emails before your items have arrived. Just to clear this up one email is asking for a company review & our service, the second would be for a review of the product you brought. We feel both of these types of reviews are essential to boost confidence of new customers and to showcase our service and the quality of the products we sell. Any feedback good or bad helps us massively so we appreciate all feedback. From your feedback we have extended the time from when orders are place to when our reveiw emails are sent. Once again thanks for taking the time to leave feedback and thanks for shopping with us.
