Yet again my aerial is down

<p>Exactly a month ago I had the same problem, and was offline for 7 days, and yesterday it happened again, my aerial is not connecting. Are you selling customers faulty equipment? How do you explain breakdowns of twice in one month of the aerial loosing signal. Please send a technician out ASAP and I expect to be reimbursed for all the days that I am off line.
