Telco companies will keep selling data as long as it's profitable. If the company continues to sell data to the offending clients despite knowingly violating its terms, then a case could be made for negligence against the telco. In my eyes this practice, like many shady data-dealings, lacks legal precedence and its profitability will change as litigation mounts against the telcos. Furthermore national laws need individual cases to gain traction. Bad practices are bound to change when a few high profile cases end up in the courts. Feels funny to say this, but it seems like the world needs more lawyers.
