Worst service ever!!

Since I switched my contract from business to personal in February this year I had endless problems. For the whole of March my line was continuously disconnected due to their poor system. As a result I spent hours on the phone, in and out of different stores to have the problem sorted. After continuous frustrations I later cancelled the contract and was informed that it will only take effect at the end of March. I was later convinced by the Sandi at the iStore in PE to take up the upgrade offer, which I duly did. Regrettably so. First it took days for Vodacom to have the cancellation reversed. After days of running around the contract was finally upgraded. Or so I thought. After signing the new contract on 27 March I was informed that the new contract will take effect 1 April. Come 1 April my contract was still not converted. This resulted in further chaos I was again sent from pillar to post. At one point I was on the line for a full hour until Santos Singh came to my 'rescue'. Or so I thought. Came midnight 4 and 5 April my line was again disconnected. Now they expect me to carry the cost for their errors. Seems like a moneymaking scheme. I've seldom experienced such incompetence
