******* Debit order

Vodacom has been really unfair towards me. I have never had a vodacom contract in my life. They debited money from my account twice. The second time I had to go to to my nearest vodacom shop. They rectified the ******* debit order but cant give me proof to supply to my bank. They said they will pay me back, 3 weeks later, and the consultant at vodacom is not getting any feedback, nor am I getting my money back. terrible service!
