Vodacom Poor Customer Service

I cancelled my Vodacom contract, which was coming to a 3 year end contract. i made an effort to call Vodacom on this matter, however, someone in Vodacom didn't their job instead they migrated the contract to another package. Now they have send the account for legal collect. I being constantly call by lawyer to collect a mere R174.98. When i call Vodacom to sort this matter, i am being taken from pillar to post. This is such a poor customer service.
