RUDE service from call center staff

I have received the WORST service from Vodacom this morning during my call to cancel one of the contracts I have with you.

Firstly I had to phone customer care to get the number I would like to cancel, since I DON'T get the statements I am suppose to get every month with the details of all the numbers. I spoke to the lady and she gave me a date of June to cancel my contract. She then said she spoke to the cancellations department and they will cancel the contract now.

She had the put me through to cancellations where I spoke to Zanele and her manager (what a rude bunch of people). They refused to really help me, then put the phone down in my ear without giving me a reference number for the call.

I have previously asked about when I am able to cancel the contract and I was told in April. This morning the date changed to June and I get this type of service. I have been with Vodacom for a very long time. I don't enjoy the service received from them.

The lady in customer care told me that I received an SMS for an upgrade on the 9th of January, surely if I am able to upgrade in January I can cancel the contract by April? I need this matter resolved and sorted ASAP! The phone call took place at around 7:43
