Bad Quality flip flops

I bought my son havianas flops last year November.

In April this year it broke and even the ones i bought on superbalist. I never knew about this returning policy up until my friend told me to take it back because its less than 6months.

I couldn't return it because of the pandemic and i was also out of work until level 3.

Now this morning i decide to go to waterfront to exchange and i get there they tell me that they only had grace period of two months... How the hell was i supposed to know that and also bare in mind the flops broke during lockdown.

To begin with the quality they provide for expensive flops is not good at all. I had mine for two months and that was the end of it. Being the loyal customer I am i still had the audacity to buy from them.

Now tell me what must I do now with broken flip flops that i paid R299 for????
