Hi, I was looking for help with solving my web host database, upon looking for a seller, I sent a couple of messages to some sellers 3 of them responded on time and got in dicussin with the 2 sellers. Both of the sellers asked for credentials to the hosting account to check on the issue and advise so I did, one got back and said he can fix it at a rate of $30, I negotiated, and he agreed on $20 and created an offer. I did not accept it as I waited to hear from the other seller, when I gave him the credentials he just said he is checking on it but later after like 3hrs he responds saying he has solved the issue, and he charges $175 - $200 he did this before we even discussed on the charges.What action should I take here
