Alexsandar (sp?) was thorough, courteous and very helpful. The answer to my question not so much. I was considering taking advantage of one of SiteGround's promotions but the wording was a little unclear to me so I called and talked to a representative to make sure if I paid for the year's plan that it would be applied to my existing plan. I was assured that it would be so I paid the fee. On the chat with Alexsandar I found out that I could not apply it to my existing plan. I was still within the cancellation period, so was able to cancel and get a refund, but was disappointed there was no solution to just transfer the payment.
