How to get a response from the support group ?

I`ve been trying to get help to actually download Adobe elements.

When I put in my details for purchase - the system says "system error". I phoned the support group and was told that the charge on my card had gone through and they were waiting for a response from me.

I queried "what response"and since then - nothing !

Not happy.... and this has now been going on two days and multiple entries to customer care....

I`m open to ideas - either I can download it, or cancel the transaction.
