Pathetic service from Elite Mobile

In 2016 I took a tablet from Elite mobile with a vodacom sim and then had it upgraded last year at Vodacom. Subsequently I've been receiving sms' for a different person, Ms. Lufuno Sa****i, from retail stores and subscriptions as well as messages from vodacom about data usage etc for a different number. I went to Vodacom to stop all subscriptions in my phone as I did't subscribe to anything but continued receiving sms' for Ms.Sa****i and notifications of deductions of emergency airtime for a different cell number to mine. I 've tried to contact Elite Mobile as I' m convinced my cell number is linked to a different number to no avail. It's now come to my attention that every month approximately R300.00 is being deducted from my bank account for apps I'm not subscribed to. I am convinced it is the subscriptions for this unknown number (Ms. SA****I) which is being deducted from my bank account. I HAVE NOT BEEN ABLE TO GET HOLD OF ELITE MOBILE. They offer pathetic service. I need help and don't know where to turn. Vodacom can't help and I can't get hold of Elite Mobile. Below is a list of subscriptions being deducted from my account for this other number linked to mine: Iwyze - R70.02 Safety Box - R56.00 Chart is Life 1 - R81.61 Chart is Life 2 - R42.88 Hotspotterem - R65.00 Halo - R49.00 So Music - R50.00 Rescue Box - R58.00

In addition to this I lose data and airtime when I'm not using my phone.
