My advice is to immediately send an email to
help@emirates.net.ae demanding a refund for internet charges levied since end Feb to the present and demanding a written answer by email. Then call 8006100 every day to complain. Every call you make is logged and becomes part of your record that you have complained. Follow up with reminder emails every other day.
Ask all your fellow (friends) who are network admins to do the same. When the noise gets loud enough they will start to panic at the bad publicity.
However the quickest way to get action is if they are publically humiliated, which they strongly need to be considering their dishonest actions.
For this a few news services need to start carrying the story of customers who are angry that they are being cheated even after paying amongst the
highest internet rates in the world to one of the highest earning companies in the world in a city where the government is encouraging the use of internet and high tech applications for commerce.
Without all this happening, they will try and give you the run around, use their usual ploy of telling you it is your problem only and that no one else is complaining.
If you keep insisting for an answer, they will grudgingly tell you it is due to an international link problem and that it will be fixed in a few days. They have used this "few days" line now since the early March - so for over 2 months now - it will be fixed in a few days.
Considering all factors and that Etisalat are so carefully wiholding the truth and not replying honestly - this strongly appears to be purposely applied Rate Limiting to earn Etisalat extra money.
How much more do they want to milk from their customers? Maybe all they can before competitors start appearing.
