no response from customer services for boots under warranty

Hi there.

Fouganza riding boots were initially purchased online on 30th July.

They were replaced on the 29/10/21 reference 6512

The replacement boots have come apart where the elastic is.

5 emails made to decathlon customer service/complaints requesting that they Please be repaired or replaced. (The decathlon fouganza brand has a 6 month wararanty - boots are 3 months old.

To date I have had no response from them at all. I am shocked and disappointed especially as we frequently buy from them.

They were requested to email on *** as cel reception is poor.
