Was trying to enhance icloud space to a 200GB plan

Hi,

5 attempts, $1 per attempt, that makes a total of $5 that I have paid to iTuens (which more amount than 200GB monthly plan)

I was promised that our representative will contact you within 7 days. 11 days already past but no response till date.
Who and on what email I may forward my request for resolution?

Any help would be highly appreciated.

Regards
