Poor service from vodacom

I'm very disappointed with the responses I have being receiving from the vodacom online team and after sales department ,I have made several calls and arrangement with different consultant everyday of last week I spent hours on calls which made no difference ,it's seem there is no process that is followed and even the managers do not like to assist on the call ,I have being trying to make arrangements for a change of address and to inform vodacom I was ****** and my I'd has being ****** ,I was put on hold for a long period of time eventually I terminated the call due to I had to get back to work or the agent advised they would follow up and call me back but nothing was done ,when I called ram courier they advised me I need to call vodacom and ask them to email ram stating i have a copy of my id and affidavit and proof of residence,i also notified vodacom on that day to change the address for delivery to my work address I was told my package was going to be delivered to me at work on Thurs or Friday butnothing was delivered ,I advised vodacom on many occasions that I work in a call center and I cannot answer calls at a certain time ,every time I called vodacom agents spoke rudely to me that not customer experience and they should be trained to do they jobs ,instead of not knowing wat to do .The agent I spoke to on Friday told me just cancel and go the store and get it done ,I have done it online for convince due to I work long hours ,payment had being taken but no device has being delivered .
