Very very bad Service

Nr. 1 my Vodacom number *** contract expired end March.. I phoned Vodacom in Februarie and 1st March to make sure this contract must be cancelled... I received sms contract is cancelled and I must add money on it to avoid number cancelled.. This month my phone number is still on my accounts.. When I phoned Vodacom number was not cancelled... Nr 2 Vodacom phoned me and please you are welcome to listen to the voicecalls to add another 5gig bonus on my 20gig and and I'm going to pay less on ***. LIEG.... On my account the amount is suddenly R300+ more.. I'm a pensioner who only received Sassa.. I asked Vodacom to please stop the 5gig with emmediate effect and they just give me excuses.. I will make sure there is NO money in my bak acxount for Vodacom account will only pay them what I was suppose to be paid... All I can think of is that the people at Vodacom are *********** and don't know how to cancell contracts... I'm so unhappy with Vodacom that I'm going to cancell ALL my contracts on expiring date and moving over to another Provider..... Too many problems with Vodacom... I will NOT pay the R300 extra for the 5gig this must be cancelled. I told the guy I dont want it ny 20gig is enough.. But he keep in telling me Im going to pay less and get more.. All lies....... I will not pay my phone number as it expires end March.... So I will only pay last months amount LESS the phone expired end March... Thank God end July there will only be one item expire next year then I close my account....My 20gig I told them must run month by month.. Dont even know if they understand what that mean.... Please people think twice before you make use of Vodacom.... There is never reception but you must pay... So many people telling me of another provider but I'm so long with Vodacom but I think it is time to say goodbye and move to another provider with better service
