still waiting to be called by the installation guy

On the 16/04 2016 i called multichoice to inform them that i want to activate my account and have my Dstv installed . The lady that i was speaking to at the call centre took down my details and contacts and informed my that within 48 hours i will receive a call from one of their guys to come and set it up . Today is the 20/04 2016 and there is still no call or feedback from them ,let alone anything just to notify us that they are delaying or whatever the reason maybe .Now i cant even watch tv because of them and we had just moved into our new place ,so we really need someone to urgently come and assist us, after all we did pay for it . This is very unprofessional of them to inconvinience us like this . I really hope that someone will acdtually do something about it today !!!
