How much longer?

I was called and offered a price-lock plan which I accepted. I was told to send an sms as soon as I receive the new decoder to get an installer to do the installation. I did sms the word help as required to do the the supp**** sms number on 15/01, and received and sms that someone will call me within 48 hours. Well nobody called me, and on 18/01 I called multichoice and at first was treated as I was at wrong, but later transferred to Mpho who said that she did instruct an installer who will call me shortly on the same day. Nobody ever called me. I called again on 19/01 in the morning, and again nobody could assist me other that to say they will esculate the query. People, how much longer must I make calls and wait. The weekend is here, and I cannot make use of my new device. I feel that nobody even listen to me
