Hi, anybody here with the same experience?

My unifi was cut off even though I was paying on time. When we called Unifi the operator said that we already upgraded to 50mbps at RM285. But was still paying the previous package of rm257 for over a year. We now owe more than Rm700 and have to pay up if we want the Internet back up.

The thing is we never agreed to any upgrade. And unaware of the upgrade. Any suggestions what are our options?
