Subway does not care about their clients!!!!

I would just like to kindly express my disgust in Subway South Africas Headoffice, I have been trying to get a hold of them for more than two weeks now and been emailing and leaving comments every where buI have not received any response from anyone there. I am a regular customer at Subway Rosebank after my first Hello Peter complaint about that store I have not been treated better since and to think that the owner of the store would try and change the complaint to a compliment it has not happened. I have been refused deliverys three times after my complaint or the manager just tells me that his staff left so I cannot be helped. Since no action was taken fron the owners side I thought let me call Headoffice but the phone is always on voicemail and no response to my emails. I cannot even begin to explain how disappointing that is from a company like Subway. Are they not supposed to care about their regular customers, I am a daily visitor at that store. I believe that action needed ti be taken immediately. Every time I pass there now there is no one exept the manager and if I order my usual crumped chicken I am told by him they are out of stock. WHAT A JOKE! Fix this
