Ruby, if you really have had enough and cancel, then VM are still obliged to pay you the requisite compensation (before April it was £5.25 per day, it's a little more now), obviously not in the form of account credit (as you won't have one) but as a cheque (yes I know, quaint but still fitting for a company whose operating procedures are stuck in the 19th Century).
In theory this is all automatic as per the guidelines which OFCOM drew up and VM agreed to, so if you were to call them and cancel tomorrow, say, and assuming that your instruction was carried out and not just ignored, then you should get a cheque for the correct amount within 30 days.
Well that's the theory, what would actually happen is probably nothing at all, or a message offering £20 as a goodwill gesture and a claim that they don't even owe you that on the grounds that it's not their fault, council permits, leaves on the line, sunspots etc! If and when that happens, you contact VM, and raise a formal complaint, probably best done in writing to their Sunderland office, rejecting any insulting compensation, or if they have simply ignored you completely, and request full payment of the delayed installation compensation owed (you can look up the current daily rate, and calculate it accordingly), the first installation date itself doesn't count, it starts from the next day, and the day you formally cancel also doesn't count, plus you add an additional £25 in recompense for the poor complaint handling and inconvenience.
Naturally this will go nowhere either but eight weeks after you make the complaint and get nowhere, you can escalate it to the Ombudsman Service where you request that VM be 'ordered' to pay you the compensation plus, by now and additional £50 for the extra inconvenience and even worse complaint handling. Their rulings can be enforced in the Courts if necessary - watching bailiffs turn up at VM HQ with police presence to arrest the security people and start removing goods to the value of.., well I'd pay good money to see that!
