Vodacom - No refund

I am highly disgusted in this Company, I have been waiting for a refund of double payment of an amount of R3100.00 since beginning of the month. I have now just received the third reference number and every time its a different story I am the one that needs to follow up to see what is happening and every time I have to hear but this and that when I have done everything that they have asked. I logged the compliant on the 30th April its the 19th May today and now I hear 14 working days! Your service is up to scratch and your customer service just as much! I am beyond upset, let me take R3100.00 out of your mouth and see how you would feel. Been a customer of yours for 23 years. They are SO quick to say you owe money and if not paid this and that, but when its owed to you they just feel NOTHING!!!! DISGUSTED and P**** Off isnt even the words i have.
