They will never, never give a specific time even though you request it. It always has to be 8-1 or 1-6 which is why I always arrange it on my day off !! Annoying just to stay in waiting which could be the end of each of these shifts.
Ive had them ring me up twice in the last month saying my service is overdue which I know it itsnt, cos its September. They ask if I would like to make an appointment over the phone. No way am I telling them when I will and will not be in !! I always book it online and mentioned this, and both times they remarked they would send me an email to do this, which still hasnt arrived.
