My plan is $50/M, but last month I was charged 76.35. Because I added a new number in my account on oct 12,I thought is add new number fee. But today I found last month is only for sept 1-30. This month again you charged $124.45 ( both my two number plan is $50 and $35 only.) what's wrong ?
Your first billing period is pro-rated from when you signed up to the billing date. You are also charged services for the upcoming month in advance This occurs when anyone signs up with a provider. Similarly, when you change a plan, both the old plan and the new are pro-rated for the portion of the month they were active. Here’s link for you describing the process.
