Been struggling for months to change surname

<p>I have logged several requests to Vodacom to change my surname on my statements and also sent the necessary documentation through. It's been months and my surname is still reflecting as my ****en surname on my statements. I have phoned on a weekly basis to follow up on my requests but no one is able to tell me the progress on my requests. This service is shockingly poor and frustrating. No one is getting back to me as they promised with any feedback and I'm fed up with phoning in and a customer service agent telling me he or she can't assist me. Is this not the function of customer service?!!!!</p>
