Vodacom ************ TACTICS

I have three contracts running with Vodacom. Recently one of said contract was due to run out. The Vodacom call center made contact with me to upgrade this contract. I asked them to please not do anything and also to not call me again and that I would go into a Vodacom branch to make changes or upgrades. Vodacom proceeded to call me more than TEN TIMES during my time at work!!! One person even told me that if I decide to not accept the upgrade and choose to go to a branch to do business, they will flag my account and I will never be able to do ANY telephonic business ever again, even in the event of theft of a device. I proceeded to take an upgrade with one of the callers eventually during my working hours (it was about the TWELFTH CALL FOR THE MORNING). I would like to make mention that I am a school teacher, so answering calls of any nature is extremely difficult for me. I see this a bullying and ************ tactic in order to make a sale because I tried to make it clear that I will go into a branch on a weekend when I have time to sort my things out. This is totally unacceptable to say the least!
