Ok, so I came to a problem with my mobile service provider. So the short version is this: In January we called our mobile service provider to ask about international roaming to a specific country. This company has service in that other country (under the same name), and since my parents know nothing about KB or MB, they asked to have a limit of $40 dollars so as to be able to call and have internet while on vacation, but as soon as they've used up their "additional charges allowance" the service would cut off. The provider agreed and the limit was set. So my parents go on vacation and had internet during 3 days from the 7 day trip, only to come back and discover that they were being charged $1500 dollars for 300 MB of data usage (mostly data from Mom using Facebook to upload the one or other picture). So I've been trying to fight this with the provider, but they allege that they cannot do anything when the services of a third-party (operator in the other country) were used. The thing here is that we were using the same operator, but in a different country. They also said that there was no way for them to limit our services when we were using other operator's networks, and that there is a delay from the point we use the other provider's network, to the point where they receive the info of what we used. To this I say that when we specified that we were going to this other country, and that we wanted to establish a limit to use for international roaming, we were never about this delay or how they cannot enforce the limit while on the other network. So does anybody here know about this? I've been trying to find some info but nothing concrete. How much time does one provider need to tell the other one about the usage? Is that not done automatically and instantly? If not, I really do have a hard time believing that in our modern world. If it is, how big is this delay? More than 48 hours? Also, if the operators work under the same name (but in different countries), are they considered a third party? I'd appreciate anyone who can enlighten me on this topic. Thanks!
