Branch and customer care shockingly bad service

Absolutely shockingly bad service. Went to Russells Potchefstroom branch on Monday 27 January 2020 to get a dining set on my current account (which is absolutely not in arrears). Handed in all my documentation, and was approved on 28 January 2020. Signed off on the agreement (contract) and the debit order. Have been told I will receive all stock on Thursday 30 January 2020. Never received a call from Russells for Delivery information. Went to the store and was told they need documentation after I already handed in everything and approval was given. Phoned customer service on Friday, and was told Delivery will contact me for Delivery details. Never received a phone call. Called customer service again today 04 January 2020 and was told that I now need to call Accounts because there is problems with my account, which is impossible, because I am not in arrears at all. What do I need to do from hereon out to ensure I receive my complete and correct order, and not pay for something that I haven't received.
