********** Contract opened with my personal details

I receive a debit order deduction of above R200 for a cellphone contract i have no knowledge of. I have no relation with vodacom, yet my personal details were used to open a cellphone contract at one of there branches. i was given the following reference number EC-0C27-2IW2Z5. I send Vodacom a mail on the 23/10/2017 never even received a phone call. I want some from Vodacom ***** department to call me regarding the above contact details are ********** 007. How can a big company like Vodacom have such a poor response turn around time especially in a ***** department where you deal with critically matters.Such matters should be address with 48 hours . Doing something as simple as initiating a phone call. Regards N Skosana
