poor customer service

come on dischem , it does not and will not take one cent from your profits, just to be kind enough to tell your regular customer the prescription has to be renewed , rather than to keep quite , telling you did us a favour last month already , and do not supply or we have to pay cash, surely when they phoned me when could not find us due to wrong initials could have told us , there is a small problems , and it would have been solved not wait till you get there and then come with customer call centre excuses and it was noted on last month slip
