It is generally best to file a chargeback with a CC within 48 hours of receiving your paper and proving that it is not a proper sale. However, the refunding process could take up to t 3 months, with the CC asking that you pay first so they can deduct it from your future charges. They do not normally refund in cash. The crediting could be a patience tester though. Some CC will not do the rebate work unless you personally follow up and force them to do it.
