Bad Customer Services

My insurance Standard bank sent me to Autoboys to fit my car window. My car window had tint on it. Autoboys came and fitted my car window without tint. I was promised by a lady called Catherine that she will contact my insurance for authorization and after that she will advise me if a voucher will be issued for me to take my car for tint. I have sent her several emails, even called her to follow up and she promised to get back to me. Its three months already and i still have not had any feedback as yet and its really frustrating that that none one gives me feedback.
