We have applied for a MR for a pip application for my son. we sent the MR recorded delivery 4 weeks ago and I have tracked it and know that it has been received but I have heard nothing from the DWA to acknowledge that we have applied for a MR. When I rang, it simply had an answerphone message saying it can take up to 6 weeks to be reconsidered. Should they acknowledge receipt of this - bit worried that we have heard nothing !
