SUPERBALIST HAS LOST IT'S FLAIR!

I have been a very loyal customer and supporter of Spree and then Superbalist for many years. I was their biggest promoter in my circle of friends, fast and easy online shopping with great service, products and returns! And then something went horribly wrong. I have had 4 very bad experiences with Superbalist in a short period of less than a month! And the best of all is the extremely *********** and unhelpful customer service staff that just refuse to help or assist. No managers are available to assist either. I am seriously disappointed and battle to stay positive about this company. First of all they were not able to assist with an incorrect size item on a final sale product, then they just cancelled an item I bought and paid for from their side and the cherry on top is that the last 2 orders that I received for Christmas gifts that I bought on the black Friday sale had items missing! This has been reported but just referred to the warehouse to investigate? So how do I prove that the items were missing? I never had this problem before? and how long will it take for the warehouse to investigate and respond? and in the meantime I paid for these items that I did not receive. Best of all we are leaving on holiday soon and there wont be anybody to receive the missing items should they be able to solve the problem this year. They are causing such an inconvenience and the purpose of online shopping is to make shopping less of an effort... totally the opposite! I just so UPSET!
