WAS cancelled after entry by my sponsor on 6th Feb...

If you mean the compensation required to be paid to the employer once the work is completed and before the term of the contract is completed here and according to the text of Article (116) of the Federal Labor Law, the article states:
Article (116):
Where a contract is revoked by the worker for reasons other than those stipulated in Article (121), he shall be required to compensate the employer for any damage the latter sustains as a result, provided that the amount of compensation shall not exceed half a month wage for three months or for the remaining period of the contract, whichever is shorter, unless otherwise stipulated in the contract.
So if you want to terminate the contract then you will be forced to pay the visa expenses, then the sponsor will ban you and you will be forced to leave the country. It is preferable to settle amicably with the work and the consortium to pay a specific amount as compensation for this employer

My dear, as long as there is no contract or visa, this means that no communications are addressed by the employer, and the matter requires review of residence and immigration, foreigners' affairs and inquiries, since the passport is not suspended unless there is a communication by the employer, and if there is a ban prohibited, its duration is a full year from the date It is approved and removed from the system automatically by the passage of this period. Thank you

If the visa expires and the ban is imposed in the country due to emergency to limit the spread of the epidemic, it should be noted that the visa can be extended automatically
Meaning, if it is ended and the residence status cannot be corrected due to the emergency situation, no fines will be imposed on you in violation of the visa and when the ban status is lifted, it can be renewed or leave the country without any restrictions on you

This report is considered malicious and may be removed by going to the labor office, knowing that if there is a ban you will not be able to get a visa, that is why we advise you to go to the labor office and explain the matter to them in detail, as they could remove it if it is proved malicious. Thank you
