Ellies/Elsat in Durban is disappointing

I bought DSTV explora with an installation voucher and I called in the Durban call centre( ‭(0861) 101-099‬ )from last week and they promised to get back to me within 24 hours. No one followed up after the TAT passed I called and the lady I spoke to said she will call back within the same day but did not. I called back again and I was just given the installer’s number to contact him myself(guess they were tired of me calling the office). I called him (Nkosi @ ‭***‬ )in the morning and he was ought to come during the day I waited and when it was late I decided to call this installer again for I could not move but wait for him. He did not answer his phone. Why are we given vouchers if it is going to be a mission to just get an installer. Can @DSTV give us another option besides these vouchers because Ellies service is ****
