Poor Service on Customer Queries

We bought a couch in the beginning of October 2021, the sales lady promised us it will be at the Boksburg Store in 18 days. We waited and 18 days later realised that it was 18 working days. After 18 working days we went to the store only to be told that the couches will be ready in a week. We made a 150km trip from Potchefstroom to Boksburg for this. Be that as it may, a week later we called the store and the manager there promised to get back to us on the inquiry and we waited in vain, causing us to drive there again on Friday(today), with another promise of another day. Why then don't you just take a deposit for the furniture you don't have and the balance when we collect, we were told to pay everything up front. Now we are incuring costs driving to Boksburg with our inquiries because your staff don't follow up on their outstanding orders or on our queries. This is totally ********* business practice.
