Couple of problems from the point of view of the client:
- It is impossible to be registered in the section of sales and at this forum if the address of mail has the new domain of the first level, for example - company. And it is interesting that on the site of support to be registered with such mail - it is possible.
- Not clearly where to address in case of problems with purchase transaction. For example if I sent the demand for the certificate, and back there is no reaction - not clearly what to do. To write support to those? There for creation of a ticket ID of the buyer which I turn out is necessary didn’t become yet. What else communication channels are?
