HIGHLY IRRITATED

So I was asked to submit documents to them. I submitted the documents and after 20 minutes I decided to give them a call. I phoned them to hear if they can just advise if they received the documentation. I'm then told they can't assist me by giving me any information on the policy. So I'm like I don't want to know about the policy I would just like to know if the documents were received. The consultant puts me through to someone else, so I start again I would just like to confirm if you received documents I have just emailed, sorry I can't see anything and I'm transferred again. So I'm by another consultant whereby I explained again what I would like this one puts me on hold. I then dropped the phone because all I would like to know if they have received the email that's all. I work in a financial institution and I mean when they phone they would like us to attend to their queries asap but all you want is just to confirm if they've received an email.
