Instant Checkmate Additional Charges after Cancellation of One Month Trial Internet

I signed up and paid, via PayPal, for a one month trial of service from Instant Checkmate. I cancelled the service within the one month time frame, as required.

After the cancellation, I was billed for an additional month. After spending time with both PayPal and Instant Checkmate, I was advised by both that no further charges would be made.

Now I have to wait three days, for what should be an immediate refund, for PayPal to credit my PayPal account; not the original source of funds. Instant Checkmate said I had TWO accounts, not the ONE I established and cancelled.

Reconsider using Instant Checkmate's "One Month Trial" offer as you may be signed up for more than one account. Reconsider using PayPal for ANY reoccurring charges to anyone.
