Items ordered and paid but not received

I ordered and paid for 2 items from Lifestyle Ltd on 08/01 - 2 Armor nail gel (R80) and 1 fake alarm beam (R220) R300 total with free postage. Immediately received a mail confirming order and tracking number. 1 week later still no parcel. Contacted via e-mail and Facebook and was assured it was sent off on 19th. Collected parcel on Thursday 28/01. Opened at home, the nail gel was missing from parcel and on the invoice I was charged R80 for postage instead. I have since then sent numerous e-mails, messages via Facebook and also tried to call them, but have had no reply. They NEVER answer their phones although they advertise they're available 24/7. I have ordered from them before with no problems, but this time their service is extremely disappointing and the fact that they ignore all requests are very infuriating. I want the items I ordered sent at no charge, since that was the original contract. If they can't do that, I want ALL my money back and they must pay for the postage to return the one item I did get.
