Ruby Aus Jaggard-Hawkins

I have paid extra contributions from Australia, I have called the help line and was told they would expedite it. I have received my original pension amount, not the top up. Does anyone actually know how long the process takes. HMRC cashed the cheque two months ago?

Im living in Australia and have just qualified for my pension. I have already contacted the overseas pension centre to confirm I can buy back sixteen years of NI contributions - the problem is I cannot get confirmation despited call the centre four weeks ago and at the moment I cannot get through die to the delays in handling incoming calls. Am I able to get clarification from HMRC on this issue - it seems the overseas centre cannot handle the volume of calls and questions and time is running out ? Any info would be really appreciated.
