Poor service

I phoned in to cancel my contract with vodacom which had ended in September ,to my knowledge and information from the consultant I dealt with there was no form of notification sent or contact made with me by vodacom to inform me that I could upgrade or if I would like to continue my contract on a month to month basis . Already frustrated at the fact that this is the second time my account has been debited with almost 3 times the amount of the initial contract I waited for 20 minutes on the line for assistance only for the retentions consultant to answer the call and when I informed her that I would like to cancel my contract she drops the line in my ear. The service received from Vodacom is absolutely pathetic , being a vodacom client for almost the past 15 years and to receive this type of service is totally unacceptable and I would never advise anyone to make use of vodacom in the future.
