Correct Ben, 100Mb shouldn't be a tier change but a manned install only during this rollout phase. Although theres nothing to stop a 100Mb tier change if the customer has the correct equipment, although if the customer had issues and downgraded to 30 then why would CS/CR change back to 100Mb without a tech roll?
And how did an engineer fix it so quickly? Surely a callout would be 24-48 hours minimum?
Trollz be lurkin here.... screenshots of a mates connection that he is flashing as his own? Or maybe he has 100Mb but just wants to chat about it? Either way, we had screenshots of speed tests of 100Mb but no evidence of the so called fluctuating speed...
