Boat — Speaker when connected with aux cable not working properly

Hi

I wanted to lodge a complaint regarding my boAt Bluetooth/wired speaker. The model name is boAt Stone 650 black colour. The problem I am facing with my speaker is as soon as I put the aux cable in the jack on the speaker a shrill sound starts to come. However, as the speaker has Bluetooth as well so when connected through Bluetooth, it plays perfectly. We had tried using many aux cables and we found out that there is some problem in the area where we put the aux cable on the speaker.

We’d bought the speaker on October 1st through amazon and the warranty card claims 1 year warrant so I hope our problem will be resolved either with a new speaker or fixing the problem in the speaker we have.

Hoping for a response.

Regards
