Worst customer service!!!!

<p>Reported a fault on Monday. Was told would be sorted within 48 hours. It's now been 4 days and still nothing. Call centre agents keep on telling me it's being attended to but no timeline can be given!!! Surely if a problem is being attended to, you should be able to give a timeline?? Even more frustrating is I'm being told "a techinician will contact you with an update but we not sure when"???? ***??? Can someone give me exact feedback on when this will be sorted???????!!!!!!!</p>
