Pathetic Fiber Service: ******* Practice

I have upgraded my Fiber from 100 Mbps to 1G Mbps. This invoice has been send and the amount has been deducted from my account. But instead, the service stayed at 100 Mbps. I have been in the WhatsApp line for the whole week, which took hours of my time as a business. So must we be happy with 10% of the service we are paying for? This is absolutely terrible. This is actually *******ion at the highest level.
