dude think about it. you bought the rank a long time ago, probably used it quite a bit, and now you want all of your money back (aka using the rank for free)? that's kind of a d--- movel
You could compare this to buying a toy from a store, using it for a while then neglecting it and moving on before deciding you want your money back, which a toy store wouldn't do, so why should mv? :p
If you chargeback you won't get the money back, Paypal protects sellers in this way I believe plus if it was a long time ago it's not worth it.
