Pathetic call centre service, especially managemen

To make a long story short. I have a problem with the purchasing and installation of a new decoder. I contacted the call centre prior to the purchase of decoder, in order to obtain all the necessary information and to avoid any inconvenience on installation. Guess what, its the 4th day and my issue still not resolved. I have spoken to 2 consultants and 4 managers, of which each one promised to come back to me, of which none have to date. Should one just accept being treated like this as a client. Never in my life have I experienced such pathetic and poor customer service and that being from the management team. The non-response is the issue that upsets me the most. Absolutely pathetic service Multichoice and I am not surprised, just judging from the numerous complaints logged on this site. Disgusted!!!
