Disgusted By The service level

Disgusted by the level of "Service" from Multichoice. They called to offer me a new explorer with price lock and they made everything sound so easy."you receive it,we send an installer and you enjoy it" I've received it over a week ago and it's still sealed in the box. To date i am still struggling to get an installer as they promised to call me. Since Monday I've called their offices more than 10 times and wasting overR300 in airtime and they make promise after promise that someone will call me and it's Wednesday Today. The last person I spoke to Yesterday (Micheal Wilson) emailed me Yesterday to say it's arranged and I can expect a call. I emailed again this Morning to inform him that I haven't received service yet and now he's just not replying. I am a client for over 10yrs and this is the service i am receiving.Total Rubish..
