Lack of communication

I ordered an item from We heart This online in October 2017. There had been a bit of a mix up with the shipping options and I thought that we would be able to resolve this quickly. I was wrong. First off I had emailed asking about my package ( about 2 weeks after hearing nothing after my order was placed and paid for) and was notified that the wrong address was given for that type of delivery selected ( which had been a glitch in the process online) and they gave me some other options. I responded asking if my package could just be posted( which is one of the options online). After two weeks of hearing nothing from them regarding the posting, I emailed again and they responded saying that was no problem, they would post it. I responded almost immediately thanking them and asking if they could just let me know when it was sent and to give me the tracking number. This all went down in about mid November. To date, I have send about 5 emails asking for these details as well as a couple Facebook messages. NO RESPONSE whatsoever. I don't understand how these people still have a business running at all. Such a simple thing for the customer to ask for and they simply cant be bothered to answer. I haven't found any other contact information for them and I am completely stuck now! I have paid for something and not received any information regarding a means of getting it.
