Clueless Vodacom does not care

So Vodacom agents can't tell me what procedures are for a earlier upgrade. My device got damaged recently so I want to pay my contract up full and do a upgrade. I've spoken to 3 agents and they all give me different stories. One says you pay your contract full and get a upgrade..another one says you have to cancel and pay in full (pay for data you would have received and then not receiving it) and then start a new contract. I can't start a new contract as I've just recently gone into sequestration. Yes financial times are hard but I've never missed payments and my payments are always on time. Vodacom you have a customer that's willing to pay up his entire contract to get a upgrade but nobody seems to care and try and help..just want to pass me on to the next consultant that has different stories than the previous one...I honestly don't care about the data you are charging me for but keeping to yourselves..just remember when I cancel my contract with you I can't open another...so you have lost a client for over 15 years..and you lost the future business we could have done
