Not calling back

Did an application in store. Was told later it was declined by customer services. Told only store could tell me why. Tried for 4 days to contact the store (Liberty Mall PMB) with over 500 calls. Phone never answered. Customer services told me they couldn't contact the store or tell me why application failed.<br> <br> Eventually did application over phone. Was declined MV***. Told only vetting could tell me what the problem was, had to do with *****? Was told Thursday that email was sent to vetting and they would call back in 24 to 48 hours ref ***. Phoned again Friday. Email sent again. Phoned on Tuesday email sent again.<br> <br> Why can't I be told what the problem is?<br> Why am I not being called back?<br> Why can't one department speak to another?
