Poor service from Essential Med

I went to Medirite pharmacy on 8 Sept 2015 to pick up my wife's chronic medication and was advised that ESSMED had terminated our membership. No previous correspondence was received from them and I have the monthly proof of payments. Membership was terminated on 24 August 2015 BUT they still debited my account on 1 September 2015. On 9 Sept 2015 I sent an e-mail requesting reasons for the termination but they nonchalantly advise that they will respond within 72 hours (even if its a chronic matter) <br> <br> I have requested their manager's contact details, but I guess he/she will avoid contact at all costs and instruct some junior clerk to handle my complaint.<br> <br> I still await some feedback.
