Not sure if this is the correct place to ask but... I have trouble with the competition creating brand confusion. When referring to their brand on twitter for example they start with my brand and then there's. One example would be If "Apple"(creator of the I-phone) would state in tweets "Microsoft/Apple" in a way to confuse people. They have stated my brand is "Dead", "Discontinued" and "No longer being maintained or developed".

I'm sure you can understand how this would help a struggling or new  brand name get recognition by using a very well known name.

When I spoke to the competition who is in Europe by the way, they state "What can one do overseas". This was of course on a non-recorded telephone conversation.

I have tried the legal channels to no avail. Any thoughts or ideas would be GREATLY appreciated. Social media can be very dangerous to any organization if used in a negative campaign.
