My LOA ends in first week of June . I called them and said I’m planning to return by third week of June . They pretty much said me Ok, we will put you back in schedule by then . It should pop up on my schedule soon else give them back a call.
I think you should follow up with them .
You called them little bit late as the schedule for the week is already set. May be that’s the reason they didn’t call you .Many stores have less hours now.
