Their customer service department is legendary among those of us who have attempted to obtain a service for vulnerable clients. Its the one time in my day job that I have totally lost my rag and triple-forted down the phone at them (with managerial assent at my end ).One of their favourite games is to assign a problem a different refernce number at each point in the audit trail so nobody knows who hadnt done s*d all about it. the nerve centre is a sehd near Birmingham -the only people who can ok a service head activation on a void property -reachable only by six week telephonic labrynth.
