Coin Master complaint: Card collection shambles

So build many villages, open up many card collections and Recieve No New Cards. I’ve been given at least thirty chests consecutively through buying, rewarded or within a raid, Not One contained a NEW CARD. What is the point of completing villages, opening card collections and NEVER having any chance to complete them. Why not stop giving repeat cards for collections that have been completed. Yesterday I had a perfect raid on 31,000000 x 2, Not given the money. Oh yes the next spin gave me the raid again but was given a chest with No New Cards, so less money gained and by the time it finished it had been stolen. Waste of time. I liked this game but now the card debacle and the glitches are making me feel I should uninstall and find a similar game. Just because I don’t buy spins doesn’t mean I should be excluded from gaining new cards. Others may be willing to put up with this or even start buying but really let’s get serious.
