Powerbeats 3 - Charging and Power On issue

I purchased the Powerbeats 3 from the Apple Store last year. They were working fine but suddenly did not want to charge or power on. I submitted them to the Apple Store to be repaired as they were under warranty.

The Apple Service and Repair center did inspect the unit and it was a factory defect, they replaced the Powerbeats 3 free of charge as they should. The same thing then happened to the new Powerbeats 3 - which was confirmed to also have then the new warranty as this was replaced with new ones.

The new Powerbeats 3 did not charge or power on - I then submitted it to the Apple Service and Repair center again - now they are claiming the charging pin is damaged and I have to pay to repair it - but it is under warranty. Ridiculous.

The internet is full of reviews confirming the Powerbeats 3 randomly stops charging and powering on.
