RL Audio FiTerra True Wireless BT 5.0 Earphones

I bought a pair of the RL True Wireless 5.0 Earphones a little over a year ago. They have been great up until a couple weeks ago. The won’t pair together any longer. I’ve been through all the steps to re-pair them together and then to my phone but have not had any luck. Any help would be appreciated. Thank you.

Bought a pair back in April. Used them consistently at the gym over the months and worked really well, until suddenly one of them stopped working completely (doesn't charge, turn on, etc so can't reset). Assumed this would be easily done as they're still under warranty, but so far not received any communication back to confirm (it's been 2 months). Better find another option if they can't promise to fulfil the warranty.

Hi disappointingly, my right bud’s button plate fell off now can this fixed ?
