Pathetic service!!

I have been a loyal customer of Vodacom for over 20 years. I have 4 contracts with them, I have not once missed a payment. *****- was committed on my profile and a number and a huge bill was added to my account. I reported it immediately and 6 weeks have passed and this is still not sorted out. Money was debited from my account and I am still waiting for my refund, I have made multiple calls. *****- was confirmed. I was told it would be deleted and again that number appears on my statement and they charge me again. I am fed up. They have records of all my conversations and what they agreed to do. I must now wait another two weeks and fill in more forms. Totally unacceptable to treat loyal customers like this. Quick to take your money but terrible at returning it!
