A patient from North Lynn has claimed he had to wait for up to an hour for an ambulance because his call was thought to be a hoax.
But emergency service officials have denied Alan Bailey’s allegation, insisting his case was properly assessed by control room staff.
Mr Bailey, 41, of Greenlands Avenue, collapsed near the Wickes store on the St Nicholas Retail Park shortly after 11pm on Saturday.
He had been walking back to his home with relatives and friends after attending the evening’s Festival Too concert in King’s Staithe Square at the time.
He said that, although an ambulance was called to the scene, crews only arrived to help him following two further calls to the East of England Ambulance Service.
And he claimed that, when they were asked what had caused the delay, paramedics said the call had been believed to be a hoax.
He said there had been occasions where his name was given by hoax callers and that he had been wrongly accused of making hoax calls himself.
He added: “They said it to my wife.”
But the trust has rejected the accusation, saying the call was categorised as a less serious case, requiring a response within 90 minutes, based on the
A spokesman said: “He was conscious and breathing and presented no immediately life-threatening symptoms.
“An ambulance crew arrived 38 minutes after the 999 call.
“He was assessed at the scene and all observations were fine.
“The patient was discharged at the scene to make a follow-up appointment with his GP.”
However, Mr Bailey has said he intends to make a formal complaint about his treatment.
He said: “I could have been half-dead. The way I see it, if someone has collapsed and they dial 999, an ambulance should come straightaway.”
