All services that we are reselling, Pro4k, V2TV, ForeverTV and QQTV, are from completely different streaming providers. We are just reselling those services and you will need to purchase each service to use it.
For example: after buying Pro4k you realize that you like QQTV better and want to switch. We cannot switch your service from Pro4k to QQTV. You will have to wait until your Pro4k subscription expired and purchase QQTV. If you buy 3 months Pro4k, we can switch 2 months to QQTV if you want but we cannot do the same with the first month of service as we already paid for the credits and cannot recover it from Pro4k.
