GOT HACKED

I recently purchased a Tactix Charlie watch and yesterday i downloaded and paid for a few watch faces, well this morning I get a message for Apple saying someone was trying to log into my account from Saudi Arabia, then while I was listening to Spotify on my phone it changes songs and it did it a few more times after that then i check my emails and spotify sent me notices that other individuals had signed to my account from Russia and also Saudi Arabia and some other place in the US cant help to think that this was all due to the garmin app.  so beware
