I cleared an interview, received an offer, & paid the consultant - but no joining updates for 3 weeks. Should I wait?

I am looking for a job, I had uploaded my resume in job site. A consultant called me & introduced himself telling he know some of the openings. He had a detailed discussion about my job & my skills. He told need to register to his consultancy for scheduling interview. I registered with him & he got me a interview. Interview was done by the company through skype. I could not see the company persons. They told only they can see me. Interview went on well & regarding salary I told my expectation but they told it is not possible & they told their proposal. Finally I agreed to them. They gave me code & told to visit the company for next round. Consultant called me after first round & told recruiter is very happy with the interview. Regarding salary he told why I agreed for the proposal,he will discuss again & asked to pay charges for some of his services which he will refund the day I visit to the company & take the orders. I paid him. He told there is a increase in salary he has discussed with recruiter & again asked for the money I did only partial payment & further will not pay anything. Second round also happened through skype instead of in person. Interview went on well & salary offered was good comparing to before & there was a big jump. Recruiter told they have planned to give additional responsibilities so they have increased. Finally they gave me a date to visit company. I asked when will I get the order, he replied he will send to consultant as I was taken by them. Till now i did not get the orders, consultant is keep on postponing. Now he told visit to company date is also postponed, he will update in next week & not to worry as job is confirmed. Now not understanding what to do, am I been cheated or wait.

Namaste, will I get the job I am looking forward. I got it from a consultant & consultant got me to the interview. Interview was done through skype, 2 rounds of interview was done. In first round they offered me the salary & in second round they offered me more salary stating that they will give additional responsibility & I was selected there. Company person told they will send the appointment letter to consultant as I was referred by them by last week but not sent. I checked with consultant he told will get this week & did not get. He told by next week he will finalise.He is not replying me properly. He asked me money & paid him a lot. He told he will refund after joining. Till now did not get appointment letter. I am cheated or I will get the job. Can I contact the company. Please suggest I am very upset.

I have been given verbal confirmation of a job by the director of the company. However, it has been a month since and I have not reeived my offer letter. I have contacted the company numerous times and they say that the HR has left the company due to medical reasons and so the delay. My joining is said to be from May. Now what should I do?
