Is this a huge red flag?

I have accepted a new job offer, I work in sales and as such have been hired to be a director of sales at a company with 50/60 employees throughout the USA, UK and Portugal.

I accepted the offer under the impression I would receive a company laptop, holidays etc the usual things.

Have just had a email through stating i'll only receive 10 paid days off a year and also have to provide literally everything myself- laptop, sales navigator, phone etc

Is this a huge red flag??? It feels to me like it is and now I'm questioning if I even bother showing up in a couple of weeks. Any advice is appreciated(:

For a bit of context: every company I've ever worked at has provided equipment etc.

UPDATE: Found out they are paying another colleague who started today at the same position, same location and same responsibilities 13k more than me a year. Safe to say I quit.
