Your BQM shows a classic over-utilisation footprint. Some earlier comments of mine apply.
Unfortunately, even in the fraction of over-utilisation cases where there is a genuine plan to do something tangible to resolve the issue, VM's total disregard for customers, a lack of any effective regulation, and a corporate culture of zero transparency means the company won't tell the affected customers. All you get is wiffle-waffle obfuscation and a fix date that keeps moving forward, and more often than not there is no plan to do anything tangible.
What are your options? You can complain to VM and then escalate to the industry arbitration scheme CISAS, but they can't force VM to invest to fix this (though they could get you released from a fixed term contract if you argue your case well).
In reality, the only option is to find another ISP that has more regard for its customers than Virgin Media. If you do this, get the Openreach connection in and working before cancelling VM, so that if there's problems with Openreach you can cancel in 14 days and stick with the rotten devil you know, And if choosing another ISP, consider the best of the smaller, customer service focused ISPs like Zen Internet, AAISP, Aquiss, uno and IDnet. Not only for better sales, provisioning and general customer service, but because although Openreach do the physical work, if there are faults then there's a big difference as to how effective different ISPs are at getting them fixed. And if choosing another ISP, check out their customer's feedback on Trustpilot. No point ending up locked into a twelve month contract with a company as bad as this one.
