Poor service levels once again!

On 12 July I went to your Hillcrest store to have my surname changed. The manager assisted me. He took copies of my ID and marriage certificate and saved it on a flash disk before submitting for the change. I was told that the change would take 3 days and my next statement would show the changed details. I received my statement but no change. I contacted Vodacom via Facebook and instead of contacting Hillcrest and querying I was asked to resubmit the info. What is the point of me wasting my time going in and now i must redo. I dont have the time for this. When I asked the person on FB for their name they first did not give me their name and on my second request ignored me. That is terrible customer service. I still have the chat and think that the person on the other side lacks customer service s****s. I want this sorted out and I have no time to resubmit as I am pregnant, almost due and think Vodacom needs to get with the programme and sort out internal incompetencies without inconcveniencing me. Poor service is exactly the reason why I havent upgraded my contract which is due for upgrade. I plan on taking my business to MTN because I no longer wish to support a company which adds no value for me. Please sort out.
