Coin Master complaint: Pattern of glitches

Several times in the past I made purchases for 2.99 and did not receive my reward which I blew off but this last time was for 6.99 and I never received it…
Therefore I was unable to complete my task and ended up being attack and losing coines time in money. It’s like pulling teeth to try and resolve it effectively I made a lot of purchases and spent a lot of money and I feel like they use that against me…. I haven’t received multiple rewards up one or at least placed into tournaments 1 of which I did not receive anything I have had attacks and not received rewards as well…. Yet I am a dummy for continuously playing but because I could not get a resolve from this particular app I had to contact my bank and now I have to wait for a full investigation which I’m sure it will not look good for me since I have had so many purchases directly with this game app so I screenshot the transaction and sent it to my bank now I have to wait 7 to 10 working days for an investigation…. Previously I contacted coin master about not receiving rewards and they told me they could not verify anything and pretty much sent me on my way. I just want my money back and I’m going to remove my card they no longer have to worry about any type of purchases for any games from this point forward.
