Vodacom : Why do u have customers deal with incompetence

On the 1st March 2018 i called Vodacom to cancel a contract they offered me a 10 gig data package. Upon receiving the package there was no sim card so how was i supposed to use it. Upon getting a sim swop i find that there is no data. The operator then tells me that the data would only kick int he next month. I called to cancel the contract . It took them an entire month and a half to send a courier and upon sending someone they sent them to Durban. Wow 800 km away from where the package was!! Talk bout mis communication. I must have called vodacom about 15 times now to fetch this package. on the 18th April they fetched the package finally and today I called vodacom to find out if my contracts were cancelled and i get shunted from pillar to post and no one has answers . Frankly i am fed up of Vodacom and their non existent service. I ask to speak to someone who can make decisions and I get told the same old answer my supervisor is in a meeting, it like the call centres agents are taught to say this ,like a stuck tape recorder . Maybe the supervisors should get out of meeting and find out what actually is happening to their customers . Get some of your managers and supervisors to call customers for reviews in order to do some improvements . This is disgraceful
