Blockchain.com complaint: Holding wire deposit on pending over a month

Hello my name is Christina Black I wired a deposit of 3700.00 to Blockchain that I’m thinking they don’t work with my bank since I seen it later on they’re list of banks they do work with because they have rejected my bank card on other accassions so I tried directly wire deposit to my blockchain account which went to Silvergate bank which they held it for three weeks they wouldn’t tell me anything the said I would have to have a bank account with them in order to tell me anything but yet they held on to my wire deposit before sending it to block chain which they were rude to me and hung up on me then I contacted my bank trying to reverse the the wire deposit of $3700.00and Silvergate bank in California told my bank they sent it to blockchain so when my blockchain started showing pending for my deposit which it was going on three weeks I actual got a text message from a Alex Thompson from blockchain support team and gave me a number to call him so I did and while on the phone with him he had me down load a app to called quick team support to fix the issue with my blockchain account he did after we were done he told me it would be fixed in one hour and if not fixed to call him back so problem wasn’t fixed I tried calling he kept dropping my calls and screening them not answering my calls so I’ve tried so many emails to blockchain the same response letting me know they are working on it so I tried calling a few times leaving messages to contact me so I just email them today that I feel the account isn’t active to just send my money back because I’m feeling like closing my account with blockchain and file a complaint against them so can yo please Help me??
