I'm fed up with DISCORD's service(About nitro payment)

I know I shouldn't even send this on this
And should seek other help
But I am convinced that this is not my problem
And i have done everything i can do
But the service of DISCORD is too much BAD
So I decided to send this post to attract their attention

(Let me start by saying my English is not very good, I use translator
I try to express all I want to say)

Below is a description of my problem
I have traded Nitro with someone for a year in the past
And there are payment pictures and I have indeed received trust points for 12 months
I hope everyone can check and tell me whether it’s my problem or discord’s problem
