I have no problem with the manner in which SlySoft conducts business. As state numerous times SlySoft is a small company with a small work force.
Hiring extra people cost money, which ultimately is passed on to the cost of their products. The cost of their software is a bargain considering what their Software does and how much money is saved when you back up a DVD.
As stated by you your purchase of AnyDVD with an American card and using a French address is out of the norm. It appears that you total purchase time to the receipt of Registration Keys took less than hour when using normal credit card and address. Why is it so a reasonable time that you need to be suggesting that SlySoft needs to hire a larger staff.
I personally want SlySoft to expend their limited resources focused on addressing technical issues with their products than running down weird purchasing events and lost registrations. If there is no issues with a credit card SlySoft provides Registration Key with in minutes of purchase. This fact has been confirmed by many Forum Members. It is only when the customer stretches the limits of SlySoft work force with wired credit card purchases and lost Registration Keys SlySoft does not respond within minutes.
As suggested by Olli you need to chill out and be reasonable with your demands of SlySoft.
