Bad service

I am deeply disappointed by the service received from service consultants, I spoke to Sisetho from customer service who was not helpful, therefore I have requested to be transferred to her team leader she informed me that her team leader is not available, I have requested for the name of the team leader she informed me that is Asanda, I have requested if he can call me back after his meeting but she opted to transfer the call to collection, which they also failed to assist and transferred to contract where I spoke to Nonhlanhla who also failed to assist as she did not understand why I was transferred to her, worst as she did not even try to access the system to understand the query, she opted to transfer me when I requested to speak to her team leader she informed me that he is not available. This kind of service is frustrating. My account has was in arrears for November,December n January on the 11 of January I received the statement which stipulated that I owed R2214, 55, on the 16th of January I called vodacom spoke to the service consultant who was very helpful and friendly she assisted me to make payment which was made in full. To my surprise this week I am receiving calls that my account is in arrears. Which was never communicated to me, I would like to refer Vodam to listen to the call I made in November where my contract was updated no such communication took place. I would like vodacom to make available the recordings were this additional billing was agreed upon failure to provide such I request the that amount be cancelled with immediate effect, it must also be placed on record that vodacom opted to upgrade my contract even though they already knew that I had financial constraints as the debit order for November was reserved at the time of the upgrade. In December I received numerous messages that my contact has been cancelled and it will not be upgraded, at no stage did I call Vodacom after receiving those messages I was at peace with the messages. Suddenly while I was at work I received a call from delivery people that my phone and WiFi will be delivered which it was done without my consent. It is very irresponsible for vodacom to be adding additional costs to my accounts. I am not liable for that payment off R200 and something I there for request that it must be written off. Should this amount not be cancelled I will escalate this matter to the regulatory based on the fact that this contract was issued prematurely. In fact vodacom should be liable for all costs due to reckless lending.
