My Qatar employment Visa is delayed.

Hello there, I am from India. I got offered a job in qatar last december. Its a company named Hamton International Wll. I dont know much details about the company except from they're MEP contractor. In the MOI website it is shown my visa is ready to print for more than one month. Visa fees has not yet paid by the sponsor. When I contact the recruiter they keep on saying it will come in a week,for last 4-5 weeks. So I would like to hear from you people about the following 1) Is it normal for employment visa delays this much?,provided,a few visa has been printed by the same company for those who got recruited along with Us. only ours are delayed. 2) If you know something about this company (Hamton international WLL. ) please share the info. after searching for hours in the website I couldn't find its International branches. Thank you.
