Call center & support questions

Why does we need use internationnal numbers to call, support lines. And when we asked 10 to 15 a line for an internationnal call to find an answer at the support, we lose more time than calling a local provider. (yes for playing music there are other address) The problem is: we are not enough interresting to have a reply from the nearest PTC office in the same city. Wow ! Our monney is not too bad enough ? Still waiting the return of the person who begun our support call two/three years ago... perhaps he lost his flying ticket ? Well for a world record, it could be one. hum... My second question is : How many times will all questions stay without replies.
