The East of England Ambulance Trust has apologised to Michala Carney for the time it took to deal with her emergency.
A spokeswoman for the Trust said; ““We would like to apologise to Miss Carney for the length of time it took to get a response to her.
“We received a 999 call at 6.36pm and, unfortunately, due to the high number of life-threatening emergencies that the Trust was dealing with at the time, it took two hours and eight minutes to get a paramedic on scene.
“This is not acceptable, and that is why we actively recruiting .
“We are also up-skilling our staff .”
The Trust said the initial 999 call was not life-threatening, and at no point was it upgraded to life-threatening.
It said the service was very busy at the time, and the first two ambulances sent to Haverhill were diverted to life-threatening calls concerning people suffering from chest pain.
The Trust added it had not received a complaint from Miss Carney about the delay.
It said it would encourage anyone who wishes to give feedback on the service they received from them on 0800 028 3382.
