Incorrect bulling with no refund in sight

Noticed that they had dropped their pricing on 200/200 fiber services but noticed my invoice was still at the old higher amount. so i logged call with them prior to the debit going through my account. 2 weeks later no feedback so sent an email to the customer services. and i was told the debit order had been adjusted but no refund was to be done. Interestingly the General Service and Terms has no mention "refunds" in its T's & C's.

I am canceling my service with them because of this.
