Frame of Poor Quality Glasses, broke in less than 2 months.

Hi Spec-Savers, I think its only fair that I make a complaint after I have contacted the store with no solution. Sadly after a terrible experience with getting my new glasses It was ready for collection since 12th Nov, 2024. Since I collected the glasses, I wore it so very little as i only wear sometimes when driving. Friday evening, 3rd, Jan, 2025, I used the glasses for driving and seems fine, didnt notice any Issue's but when I was done driving and took the glassess of my face, I noticed the arm on the left ear was cracked and fell off. I can only assume this is due to the poor quality frame as it did not bend or break or fell in any way. it did sit quite tight when worn, but didnt bother me. since the glasses is less than 2 months old and I had paid cash for it, I would assume it had some sort of guarantee, as per the CPA, the lady that assisted me told me there is no guarantee and no insurance. This is extremely poor service and sad that we are sold such poor quality products by Specsavers. that is unable to last for atleast 3 to 6 months? the Bad service is from your Zevenwatch Mall, Kuilsriver Branch. Question is what am I to do, spend more money on a new frame?
