Bad quality shoes and no after sales service

I received a pair of Merrell Intercept Granite shoes purchased in May 2021(unfortunately I don't have the invoice as it was a present) Both sides of the shoes at the toes started tearing after about 12 months. I thought as Merrell is a good quality shoe the tear wouldn't go further, but now the tears are about 40mm long. I contacted Merrell via their website and by e-mail but have received no response up to now. I paid R2200.00 for the shoes and feel that being a good quality shoe they should last much longer.
