OPSM clueless when it comes to support for Oakley glasses ?

Love my perscription Oakley glasses, one of only brands I can wear conformably with my work gear, but time and time again I always seem to be let down by OPSM in consumable parts replaced such as nose pieces and side rubber grips. I am sure this this forms part of their "Free lifetime cleaning and adjustments" policy too. Now AliExpress has the OEM parts for $10-$20 but not everyone has the tools for DIY or should have to pay for a service offered for free as part of buying their product.

I own a 2 pairs pairs of Oakley perscription glasses from OPSM, all still available to buy on their website, 1 is approx under 2years old.

Now most of the Oakley perscription glasses have 1-3 types of nose pieces, so you would assume they would have some on hand like with other brands. Side rubber grips I can sort of understand it will take longer to source as some can be unique.

But any store i go to in Auckland seems to be clueless when it comes to consumables for these glasses.

Example scenarios:

Do you have xx part? if you don't have it can you check if other stores have it?

" Sorry, we can't see spares/consumables for other stores, you need to go there an check with them.

Can you replace these nose pieces for me ?

Store 1: "can't source them, they are part of the frame you must get "new frames" from us.

Store 2: " out of stock, we don't know when they come in, we only get a handful every few months if we're lucky, try your luck in xx week"

Store 3: "never seen these style nose pieces before but we can install these non Oakley air cushion ones temporarily and you can try other stores"

Store 4: "we can order these for you but unsure when they will come in, we will contact you".... After 6 weeks store 4 calls me to come have them installed..they find out they have ordered the wrong type. 4 weeks later the right ones comes in. So 10 weeks for some nose pieces!

Anyone else have Oakley glasses from OPSM have to go through this shitshow for replacement consumables?
