@voxy is there an issue the bolt on accounts?
Pure speculation on my side but I would imagine that BoltOn accounts were conceved to suck up the slack out side of bussiness hours, hence beint 6PM to 6AM.
With the advent and growth of streaming that slack no longer exists and in certain places, such as Cape Town, the off peak times have now become peak time, consuming more bandwith than the business hours.
If that is the case then the Bolt On accounts are probably shaped to favour the primary accounts.
More IPC is the only solution for the users but is a major cost for the business.
One could say they should have planed for it but the internet is so dynamic even the most agile companies can't keep up.
South African telecoms can hardly be considered agile when it is subject to the whims of a telecommunications department that is still debating if carrier pigeons require a VAN's license.
