Vodacom IS THE WORST !!!!!!!

I am so disappointed with Vodacom after being a loyal customer of them for almost 11years they really disappointed me this past Month!! My account was in arears in August as my debit order did not go off I went to Vodacom on the 28th of August and I paid the full amount. But when the 1st of September came the debited my account twice. I have been to the Vodacom shops I have spoken to almost everyone that works for Vodacom's customer care line. My request for a refund has been logged Numerous times and I still have not received my refund it is almost a full month since I requested my refund and still nothing. Thanks Vodacom I will never again refer you to anyone!!!!
