"Lack of clear information"

I attended the day service unit on Friday 7th August with a testes tumour referred from my GP. No blood proteins had been done so these where done onsite on the day. I was assured they needed me in asap for the operation and my direct number was taken so i could be informed of the results of my test and the date for the operation which i was told would be in a matter of days. It's now midway through the week and i've had no call, can get nobody on the phone to tell me what's going on and to add insult to injury i've had a follow up appointment received for 22nd August in 2 weeks time and no details as to why? To put someone through this, scare the hell out of them with perceived urgency in the hospital and completely fail to follow through on promises is massively disappointing and outright insensitive to what is a huge scare for me.
