False advertising & hopeless customer care - Builders warehouse

Not as advertised - don't read their own fine print! I have purchased a Jojo tank from bBuilders warehouse Northriding. Advertised with free plastic tap, but this is also advertised is inclusive of a brass tap. After delivery, I called the store and advised them that they did not include none of the taps or fittings were delivered,the gentleman apologized and arranged that this be delivered same day, they only delivered the free plastic tap but not the brass tap that is included in the price. I logged a complaint on the Builders warehouse site. The Complaints department reached out - even worse!!! They couldn't even navigate their own site and once I've explained to them, the one person acknowledged that i was right but later denied when speaking to who I thnk was his superior. I told this person John Hammond which now I have a complaint against him that works in the Complaints department. When they denied that person one acknowledged, I told him to pull the call recording because they were making me out to be making nonsense up!!! John was to call me back thereafter to which he didn't. Three days later I've sent a follow up email to which no response. A lady from Builders warehouse called me for clarity, she went to the site and assured that infact yes, they messed up and promised to make good on this on the Monday, no call nothing!!!! What are they hiding, seems like they buying time to fix their false advertising, but I have screen shots which I've also sent to John Hammond - The walking complaint that works in the Complaints department.
