Vodacom suck

This will be the second time I am giving vodacom the poorest rating of service ever. I wanted to upgrade after 2 years of paying my vodacom contract on time each month. Then they told me I can only upgrade a sim card because they have put me onthe lowest credit score with them. They tried logging calls and would give feedback but nothing. Everytime I phoned I spoke to someone else and no one seemed little bit enthusiastic to just assist ,so then I told them I will cancel the contract. I did everything ,even got sms that stated that my number was now switched to prepaid,funny thing is vodacom took my debit order amount once again this month. They do not wanna give service and support but oh my goodness they want money money money. I stopped the debit order and believe me I will go to court if they try to take it again next month. I will never ever be a vodacom client ever. They suck.
