Panarotti Wild Coast doesnt value feedback

After having two bad experiences at this branch i decided to formally complain on their webpage, with the hope of being contacted so that i may give my constructive critism and feedback. The end result would have been a learning for them and that no other customer would have to experience what i did. Since writing my complaint i have been contacted by the customer contact centre three times enquiring if anyone from the branch had made contact yet. sadly its been a week and branch manager, area manager nor Regional manager have found it fit to contact me. Guess my feedback isnt as valued as i thought. Rest assured I will spread the negative word about your branch and though you will run your business as normal people will hear me.
