Worse Service ever

I have been calling these people since Thursday last week to clear simple error E16 .Now they are extremely busy to take calls. I tried their WhatsApp number ,their *120*68584# ,I spoke to 3 officials already last night I was told it was escalated and it will be cleared but till now nothing

It is annoying to call service provider to provide service you pay for, Multichoice, I am soooooo sick of this .Sort out this Notification of yours.

Please credit me as of last week and get your system to work because you retrenched people and replaced then with non functional system
