Waiting for Referral

My Partner went into the Mater Private in Dublin and his urologist performed a cystoscopy in November and a second cystoscopy on 4th Jan 24. On 5th Jan he was diagnosed with bladder cancer. At that time his urologist told him that he was referring him to a colleague of his and would be in touch in 2/3 weeks.. The urologist was on a months' annual leave in January and was back on 2nd February. My partner sent an email at the beginning of February asking for his referral, he has not got a response and he does not know the name of the oncologist he is being referred to.
He has been ringing the urologist's secretary but is not getting anywhere. He is being tole he is on a list. Given his diagnosis I am very anxious at this stage and I would very much appreciate your help in any way to how to get a response. I would be grateful if you could let me know if there is anything we can do.
