Unresolved issue from Vodacom

I have been receiving other cell no's notifications. All their notifications on how much data is remaining on their cell no's from 200mb down and then every time it goes down till they have run out of data. I have logged calls with Vodacom 1st Call/SMS - 07 December 2018 @ 15:49 Ref no. 1- ********** ********** My query has been escalated to one of Vodacom's Solutions Expert.

2nd SMS - 07 December 2018 @ 21:07 Ref no. 1- ********** ********** Please note that your service request is still in progress and being adressed.

4th SMS - 12 December 2018 @ 12:00 Ref no. 1- ********** ********** Your query has been closed.

And yet still i'm receiving the other no's notifications. Nothing resolved.

5th Call/SMS - 14 January 2019 @ 13:09 Ref. no. 1- ********** ********** Your query has been resolved.

6th SMS - 15 January 2019 @ 14:00 Ref. no. 1- ********** ********** Your query has been closed.

Now from the 15th January 2019 to 21st January 2019 i have received more than 30 sms/notifications of other no's. who's data is running out and who's buying airtime advance. I have asked Vodacom to disable those no's notifications from my cell no. and yet i'm still receiving numerous sms/notifications everyday.

Where to from here???????
