I spoke to VM on 27/1 to complain about their poor download speeds in the evening, (which BTW I am currently monitoring on an automated basis and it falls off a cliff between 6pm to 11pm) and they promised to rebate me until it was fixed, which at the time they reassured me would be "early Feb". Needless to say that (a) it has not been fixed and (b) when I received my bill no rebate had been applied. However when I spoke to them again today, they were more efficient and forthcoming and have provided a rebate of ?7.50 per month, backdated to 27/1 and fixed in place until 19th May which is when they expect the capacity issues to be resolved.
