Hi I sent off all my documents which were signed for on June 12th and had my documents returned 20th August yet I still have had no news from Concentrix about my tax credit investigation. I am expecting an overpayment on my working tax credits (I sent a full explanation and apology for not informing them of a change in working hours) but I am a bit concerned that everyone else seems to have had their cases dealt with and mine isn't. I just get told to call back when I get through on their help line and getting any sort of consistent answer is impossible. Have they just decided to abandon cases now? I wouldn't be surprised if they are now inundated with mandatory reconsiderations and complaints and I am now at the bottom of the queue! How does it take 3 months to get nowhere!!
