"Poor communication"

I usually communicate with Avenue House by email and have had responses from them in the past. Recently I sent an email regarding information on my medical records and asked for this to be passed on to a Psychiatrist I saw in the past 2 weeks. I have not received a response, even though I have followed this up a few times. 

All I have asked for is confirmation that my email has been received and passed to the Psychiatrist, but still have heard nothing with regard to this. 

Additionally, I copied in the manager of Avenue House in one of my emails, but this failed to send. 

It has been very frustrating and stressful trying to communicate with this service. Being a mental health service provider, they should be aware that service users have different communication requirements and at least acknowledge emails when received.
