First and foremost, you say yourself to be a Fresher but your opinions seem that you are a highly experienced professional. In just 2-3 days of your service that too by working from home, you are giving declarations about an organizations work culture and management. Shocking enough! You must gain some experience first to add some value to any opinion you give, as opining is good but a wrong one can cause harm to others.
When you speak about salary, it is very transparent that the offered salary was up to your expectations which was the reason you accepted it. And when you speak about training, you must know what you shall expect when being trained. A training will always be provided about the domain you’re in that was SEO, not on computer basics like how to duplicate an excel sheet. This is a skill that a company always expect an SEO person to possess. Moreover you shall refrain from such acts of giving false accusations of deduction as you know very well what has been stated to you. The behaviour that you have shown was quite unprofessional and arrogant. So you must work on it and improve yourself before hunting for a next job. All the best !
