Missing 1.7-2million coins

EA_Darko​ ive had between 4.5 million coins and 4.8 million coins for the past month or so just waiting for tots too come out and just tried making a few extra coins in time for the prem tots coming out but ive double checked my club. transfer list and  quick sell recovery and there are no drogba cards of any kind.i am also able too open my saved packs which indicates there is nothing in my unassigned tab either.I had 3.6million coins after purchasing a few drogbas and I also had 2 drogba cards on the transfer list waiting to sell at this point at between 720k and 760k each. which would bring my coupon total up and around the 5million coin mark, I bought quite a few more roughly 8-13 in total over this 1 hour period as they were as low as 600k and I was selling them between 700k-760k per card. it wasn't until the last 3 I purchased that I realised that I was missing over 1.7million coins as the coin total never rose up from the amount I had after purchasing all the cards and and selling them. just a very frustrating situation as I was just trying to make some extra coins through trading cards. any help is much appreciated
