    Dear Mr. Rafiq



The reason of suspicion for Datanet Corporation are as following :



First of all was the unusual graph type. If you see the graph you will find
that they are using symmetric bandwidth. For your reference I am attaching
the graph with the mail.



Second of all if you check in the picture you will see that just above the
week

26 there is a downtime for almost a day. During this time we blocked the
specific VOIP ports and all their traffic dropped without any reason.



These are the reasons we the NOC of TCL have suspected Datanet for doing
illegal voip termination or generation.



As per BRTC we will not allow this type of activities through our network.

Now from the above issue if you ensure us that you will not do any illegal
operation we will open the link again.



This is for your kind information.





Thanks.

    Dear Mr. Zia,

  Where is the symmetric bandwidth graph? From your graph our maximum usage
of download is 1.26 M where maximum upload is 588.80k. Does it seems as
symmetric? As your company brought some high-end technical hands, we think
its totally nonsense that this graph can call as symmetric bandwidth usage.

You just did a great mistake or may be doing fun with business Mr. Zia, as
you told you block specified VOIP ports. Doesn't your technical team know
which ports are used for VOIP purpose? we'd mailed from
datanet.noc at gmail.com and also a support ticket is generated according the
mail. There we showed what you company did, to block my traffic. Is the UDP
53 port used for voip purpose?

Again you send a support person to my office at morning 28 June, whereas you
cut-off my link on 26 June. Isn't it shows that you are cheating with us?

Below is the complain mail that I send to you support on date June 27.

Attention: Management of TELNET

We are having prblem on your service from yeasterday night. We call support
several time but no solution yet.

Every time we call, your support tel that this is our problem. So I do some
test to find problem is. I check everyting of our netowrk. There is no
problem of configuration. All time your support tell me this is my problem.
BUT problem is at your network configuration.

This is verymuch unexpected from Telnet that you are BLOCKING our Internet
Service. Specially UDP data. From yeasterday night all of my client cannot
use internet. I found that UDP Protocol is totally blocked. I want
explanation of this blockage. Please take action to your system admin who do
this.

We have lost a very big number of clients by today due to the problem of
Your internet service.

See bellow the proof of this problem:

We hope it is not done intentionally, may be configuration problem of your
router end. REMOVE the blockage ASAP and take action who done it.

Tell me Mr. Zia what the above report says? Just nothing you blocked all my
UDP packets. Is it possible after filter my all UDP packets I can use the
bandwidth?

Now, Mr. Zia, what kind of support it is that without any prior notice you
just cut-off my link as we are a licensed ISP, we've full agreement with you
according government laws and we paid full amount of bandwidth cost as
prepaid.

It is now clear to us that all this matter just happened intentionally. Your
company do this to hamper our clients, so that you can sell them your
products. I am now completely worry about your other clients who are also in
this industry, what happened on their fate? And I am asking for the
compensation that you did by hampering our business. Hope this mail is
enough, otherwise we will looking for some legal procedure.
