disgusting customer service

Once again some really disgusting customer service from you guys. I went into your menlyn store today to give notice that i want my contract closed after the 24 month period which is in august. I sat there for 40 minutes!!!! and my query wasnt even sorted out. It firstly took a few explanations to advise your consultant that i have to give notice if i want my contract closed after the 2 years otherwise you just keep it open. then i had to wait about 10 minutes for her to figure out how to dial the extension for the retentions department. then while we were holding, she was sitting there stuffing her face with eet sum mores to such an extend that i could see it in her mouth because apparently she cant chew with it closed. between mouth fulls she kept on saying how much i and the retentions call centre are boring her in her language thinking i wouldn't understand. well surprise surprise i passed zulu with distinctions in school so i understood her entire conversation. i had to leave after 40 minutes and i was advised she will call me with a reference number... guess what, no call. please just do me a favour and make my contract is closed next month. i am done with u!!!!
