Red Mage Problem

What you bought seems to be a level 70 job skip but this is not the same as Main Story Quest skip. If you wish to skip to level 70 MSQ then you also need to buy an MSQ skip or you'll have to do all the story quests starting from low level ones.

This is what it says:
Description
Use this item and learn everything you need to begin your adventure as a level 70 red mage.
This item will instantly level red mage to 70 and complete all job quests up through "With Heart and Steel."

Yes, you can adventure as a level 70 red mage. If you wanted to skip msq to level 70 as well you need the job boost as well as the story skip.

Ok. Thanks all most appreciated.

Exactly, it says "all JOB quests". Job quests are basically necessary side quests that allow you to learn more skills and learn more about your job. And those quests were skipped when you used the boost.
Main Story Quests are exactly what their name is - main quests of the game. Those can only be skipped by using an MSQ skip which is not the same as lvl 70 job boost.
