A 9 kyu played a 7 kyu and lost two games, why are we talking about sandbagging? I don't understand.
In the first game, the reason for the loss is that white played a very complicated joseki and it didn't go very well. At that point white could have cut his losses but instead tried to trick the opponent and even played out a ladder that didn't work. It happens to everyone but some games are meant to be resigned early.
In the second game, the reason for the loss (or the beginning of white's trouble) is that white tried to make a group in every part of the board. By move 30 there are 5 white groups, by move 50 there are 6, and at one point there are 8 white groups (two of them are already dead). It is almost effortless for black who just seems to be taking care of his own group's until white self-destructed. Black failed to kill white at move 113, which is indicative of how relaxed black is. Black also made a very funny move once it was really all over.

It is not so unusual to self-destruct when playing, especially when playing for fun online. I probably self-destruct once every 10-20 games myself. It is just part of the experience, just try not feel too bad about it.
