Got an automated reply to phone a number for assistance. Emailed back and said I was hard of hearing and since all the details were on the e-mail sent to them, and to which they rep****, I did not see why I should phone. No reply and still getting this message<br> This is the message and some of the points I mention in my e-mail <br> \" A special offer just for you to save BIG!
