WiLine Networks review: Automatic contract renewal without notice and large price increases

Our company signed up with Wiline in 2017 for a three year internet service contract (acct #921405). In May 2023, our contract auto renewed for three more years. We pay the charges on an annual basis to take advantage of the discount Wiline offers. In Nov 2022, we paid $2,390.82 based on Wiline's invoice covering service period 1/1/23 - 12/31/23. We thought the payment would cover the charges to the end of 2023. However, right after we sent in the annual payment, Wiline raised the monthly charge by 8% in Dec 2022, and then raised the charge again by 13.3% in Jun 2023. Our monthly charge went from $199.23 to $247.65 in less than 7 months, an increase of more than 24%. We emailed and called the billing and contract department at Wiline about the large and rapid increases. The manager tells me the increases are allowed by the contract; if we want to cancel the contract, we'd owe more than $8,000 as our contract just renewed in May. The company is unwilling to offer us any options even though we have been a customer for more than 6 years. This is a very deceptive business practice because Wiline sends us an invoice showing the service period and the amount for a 12 months period. After that, we got a one liner notification on the back page of the statement "Rate Change Notice". There's no detail of what % and how often. We feel we have no ability to budget our internet expenditures because Wiline can increase the charge anytime for any amount.
