Your BQM shows a typical over-utilisation pattern, meaning more traffic than VM's local network can handle. See how it's peachy from half midnight to waking up time? Means everything's working fine when there's not too much traffic. Nothing you can do to improve matters. In some areas VM will undertake work to rejig the local networks to balance loads and eliminate over-utilisation. But sometimes/often that's either not possible, or judged uneconomic if there's a need to spend money on more equipment. And sadly VM won't ever admit the truth, so with a fault reference and a "fix date", there's no way of knowing if that fix date is actually backed by an actual plan of action and programme of works. Quite often it seem not, and as the fix date approaches it is simply moved a month or two ahead. If there's no fault reference then it'll never be fixed, and even forum staff will be under orders not to admit there's a problem, regardless of the evidence of your BQM. Your options:
1) Sit it out, and hope that either VM do carry out improvement works. There's little or nothing you can do to force VM to upgrade the network, nor to be honest about the outlook.
2) Get yourself a new ISP. If you're in a fixed term contract you'll probably have to use the VM complaints process (and almost certainly escalate for arbitration by Ombudsman Services) to be released from contract without penalty. If you need to do this, the grounds of your complaint is the poor performance, and your request for release from contract without penalty is twofold: First the Consumer Rights Act 2015 that requires any consumer service to be provided with "reasonable skill and care", and second, the Ofcom Fairness Commitments, that state "Customers’ services work as promised, reliably over time. If things go wrong providers give a prompt response to fix problems and take appropriate action to help their customers, which may include providing compensation where relevant. If providers can’t fix problems with core services they have promised to deliver within a reasonable period, customers can walk away from their contract with no penalty."
