Terrible quality ring

Good day,

I purchased an engagement ring from your Cradlestone store on 11 December 2018, since then the resizing took 2 weeks (I was told 3 days), subsequently a few of the cubic zirconias fell out in March, the ring was returned and again the ring was in for repairs for 2 weeks (was told 1 week), the ring was only returned after a fight, now the ring is broken again (a portion of rose gold has fallen off) and the ring is nearing the end of the 6 month return period, given that your philosophy is one of "quality and craftsmanship" I am highly disappointed - given my experience I am going to return the ring and then next month when the next part falls off or breaks I am going to have to pay for the repairs on what is clearly a faulty product. . . .
