Unfriendly and unqualified helpdesk staff

Why must I wait for 4 hours in total to try and get two issues sorted. And both is still not sorted!! <br> <br> My card is blocked. The store said Edgars tried to phone, because of a high value purchase, but could not get hold of me. Please unblock my card.<br> <br> Issue 2: A jet cashier convinced me to become an Club Member because I will save on a purchase I made. She told me just to come back to the store the next day and cancel the membership. Well, I did that and received no service. Struggled for two days now to cancel the membership. <br> So, please unblock my card and end my Jet Club membership.<br> <br>
