The credit card company would not do a charge back since the service paid for was actually provided, unless you are suggesting that the card is worth several hundred dollars, and comes with free training.
Without the card (or a referral), the training did not occur and is worthless. It seems to me the op was quite clear in what he needed and when and the shop looks like it will fail to meet those conditions. If there is enough time, the instructor might be able to provide a referral but that may be undwer the control of the LDS owner also.
