Sent payments have been pending for months

i have sent usdc and eth to my meta mask account i tried to convert it to another currency and it will not allow me to i have enough eth to cover the fees and then some so there is 0 reason on my none of my sent payments go thru. i tried to send some more today from metamask to coinbase and it still isnt sending my payments.why is this? site is seeming like a straight up scam at the moment and i will never use this shit of a website again. you guys are scamming people and its pathetic. send my payments and quit being fuck niggas

i sent a payment 3 months ago and its still pending while using the fastest gas fee so makes no sense to my why the FASTEST transaction option takes 3 months and still isnt sent?
