Unsatisfactory customers service

<p>I order a bluetooth sinotec soundbar from hifi corporation online. After a few days they inform me they have a problem with stock .How can they advertise but have no stock available. How many shops do hifi corporation have around the country.I am sure they could arrange something. If a product is advertise and suddenly no stock is available it is false adverti*****t.My order number is ********** 56 W PRETORIUS </p>
