Let me preface the post by saying I have never lodged a formal complaint in my life and I'm unsure if that's the right course of action.
I recently attended a course (paid for by my employer) which involves completing a portfolio. It's very technical, involves the use of specific softwares and it's time consuming. It's delivered by an external provider.
The first trainer was uninspiring, read slides, didn't explain what he was projecting. He was then replaced by another trainer, who was quite good and clear but only attended for one day. The last day another new trainer was sent to complete the lectures.
On the last day, one of the provider's managers came on video to apologise about the delivery and offered extra sessions to catch up. There was a lot of complaining from the attending students and I decided to attend one day out of the ones offered.
I'm now going through the tasks and they are being sent back. What worries me is that the feedback I'm receiving is completely at odds with the information we received during the course. For example, the trainers said: ' X is a number and is black', but the portfolio marker says 'X is word and is white therefore your task is not correct'.
What do I do now? I already look like a tool to my employer for saying I needed to attend a top-up day, I'm now confused and have to clue how to approach the issue.
