Poor service delivery

Called Vodacom in February to cancel a contract, call got disconnected and no callback - also unable to contact the call centre again as line kept on going dead. On 14 March i got hold of an agent that promised cancellation - but only end of April - however he could see the request in Feb and said they will try to cancel by March and keep me posted. 8 days later -still not cancelled and as per my usual experience from Vodacom also no feedback received
