Prokard Explorer bad service

<p>I have been a member of Prokard membership for a number of years and have been very happy with the service I have been getting until recently. I have made a booking at a hotel using my pay for 1 stay 1 free voucher. And for the first time ever i tried to see if i can get a rate per day cheaper anywere else, as prokard has a Best Price Guarantee policy for members. I surprisngly I did find it cheaper. I informed them about it and the customer service agent came up with a list of excuses why Best Price Guarantee does not apply to my instance. I found the lower price on Marriott Groups site and was told that Marriott group is part of Protea Hotel therefore The policy dont apply. I asked her to poit this exclusionary clause out within their T&C'S and was informed their is no exclusionary clause. I was then informed that the policy dont apply when using a voucher, I once again asked her to show me the exclusionary clause does not exist. My question is how can this impact my membership negativly if the policy is not excluded in their T&C's. I have noticed a considerable negative change since the company has merged with the Mariott Group. I will have to refer this matter to the Consumer Protection Commision or for civil litigation. </p>
