No stock - No help

I'm not one to ever complain, but seeing as I'm not the only one with this problem it has to be said. I've ordered many things online and have never had any problems. On the 6th of Aug 2015 I ordered something from Homemark (order nr 35450) and paid via credit card and received the confirmation email stating that delivery will take 3-5 working days. After emailing them back twice (the confirmation email states that you can reply for questions), so I asked for a tracking number or just some confirmation of when it will be sent. This I did twice, with the last time on Monday the 10th of Aug. After no response at all we phoned the customer service number and eventually spoke to Nobi who I see everyone spoke to. After 3 calls when she asked us to phone back the next morning when she might have info regarding my order. So we did and she said the product is out of stock and I can let her know if I want a refund or to wait without an indication as to how long I will have to wait. I just want the product which I paid a lot for please, this is ridiculous.
