Product broke just after 30 days and can't be exchanged because of their 30 day exchange policy

I bought a bath ring for my 8 month old son in October on the 25th 2017. Just after 30 days on November the 30th 2017 one of the suction cups broke off. I went back to complain about it and to ask for an exchange but unfortunately they couldn't help me because of their 30 day exchange policy. CAN I HELP THAT THE PRODUCT BROKE JUST AFTER 30 DAYS??!! A few weeks later another suction cup broke off and today another one broke off. So now there's only one suction cup left on the bath ring which makes it USELESS to use for my baby. What am I supposed to do now? I thought this was a good quality product but I'm highly disappointed with the product and about the 30 day exchange policy that this shop have on their products.
