"Not happy!"

I had wrote a review previously in December, for how well the doctors had treated me. And that i was awaiting a letter for a ECHO scan. 9 months later i have still not recieved any letter. I am not happy about this, as i have previously contacted Leighton Hospital wondering where my letter is. I had been transfered through to some lady, which had been put straight to answer phone. I had left a message to arrange for the doctor/nurse to call be back, i havent heard anything since. I have been waiting expecting the letter to come but i have heard nothing. I am not happy with this due to it being to do with pleurisy on my lungs/
