Unsolicited sms's & no one answering customer care

This daily sms **** must stop!!! Nobody has time to read the same sms day in and day out without having an OPT OUT option.!!Last night I received 3 sms's while sleeping, the earliest being 04:35! Some of us are sleeping!!!! Two more came through at 05:18! I have requested via the customer care line 173 to be removed from the senders list last week on 27 March 2015 and a complaint was laid under ref nr SMC*** due to this ******* disturbing my much needed sleep. The call centre agent assured me that the change would be affected in 2 - 24 hours. But I am still receiving up to 4 sms's daily and in the middle of the night! <br> <br> The best of all when I phoned 173 this morning there were no option to be transferred to a call centre agent!!! So how do I how get this nonsense sorted out?! I must have been imagining calling on 27 March 2015!!
