Poor customer service

Unfortunately trying to contact Manicaa through normal support channels have proven fruitless - it seems they respond on hello peter, so using this now as it seems to be their primary contact channel based on other reviews. Ordered an "in stock" item last week. Got a mail a few days later to indicate they were actually out of stock, with a suggested replacement item. I responded that if delivery was a day or 2 to proceed, otherwise refund, and have followed up 2 more times after that, and no response as yet. The original reason for the order and placing it with Manicaa was due to the urgency of the order, and i have had NO luck in getting any response. Something that should have been delivered in a day or 2 is now nearing 2 weeks, with no status as to what is going on.
