Unhappy service

I wanted to apply for the deal they advertise in the brochure for the sony experia XA1 with the PlayStation 4 for the amount of R350,00 per month , I went there loving the deal and they told me I qualify for the deal however they told me that they dont have stock they need to order , I then said its fine I will wait . I went back after a week and 2 days then they told me the only have the PlayStation 4 and not the phone . So they told me that the sony Xperia xa1 is discontinued. They said sony are being discontinued from the market. They told me I qualify for the deal where they new that the phone are discontinued and I am not happy at all . I wanted that deal because I knew its worth it .
