Bad Service.

For the past 2 weeks I have been trying to get my money back since I was trying to pay my arrears and it happens that on the 1st of November they deducted their money while I used the Vodacom app to pay half of my arrears on the 28th October and I have been calling and sending emails of my bank statement to show that Vodacom owes me but I have had any luck and this is the 3rd week now . I wonder if they know that I need that money for transport to work and be able to pay them month end before they start calling. I'm really annoyed that such a thing could take 5 years to resolve but I used their app to pay and they can't even track my money . I'm really not going to let this go.
