Gameloft — Re: Progress/Item Lost Issues - Progress was reset to the beginning

When I play modern combat on 30 May then I have almost all guns unlocked (lava grinder, grinder, whisperer, vice, Lux atrena.etc.), I have more than 113k diamonds and approximately 800 eagle coins.I was of 140 level with a user name 'DARK LEGEND'.I have already bought all characters packs.But on 31 May my progress was reset and I lost everything I had once.And I was playing this game for 4 years.It is my request to you to make things right immediately.
I'll be waiting for your response.And i hope that you will find a solution.In attached photo you can see my achievements in 4 years
