Absolutely Useless

Because of Vodacoms Double Debit last month I am now struggling to get finance because of their issue. I have requested a letter on a Vodacom letterhead stating that there was an issue on their system and that they wrongfully debited by account twice. <br> <br> After logging a call on 12th January i was told that I would have my letter ready and sent within 24 to 48 hours. It is now the 18th and still the request is PENDING. <br> <br> I have called the call center that has sent me over to every possible department but absolutely nobody can help. Every manager says they will contact you but never does. I have called everyday and spent literally HOURS trying to find somebody that is capable of doing their job but still NOTHING! I have contacted head office but they put you back to customer service.<br> <br> I am seriously gobsmacked at the incompetence of the service reps that it is a laughing matter.<br> <br> HOW DIFFICULT IS IT TO GET A LETTER?????
