the format your question is in doesn't make much sense but the way that this sentence would make sense is by adding the word "quise".
la forma en cual pusiste tu pregunta no hace mucho sentido asi que trate de contestar lo mas que pude, y solo tenias que agregar la palabra "quise".
Esta semana, you quise llamarte varias veces por telefono pero estuve ocupadísima.
This is already singular. The plural is
?Compraste aquellos trajes marrones?
Which would translate as: Did you buy those brown suits?
