disgusting attitute towards customers

what the hell did i just experience from a consultant called Itumeleng collections department Cell c. i have been having a query for the past two month regarding my expired contract which cell c billed me charging me extremely high. Nothandazo from social media desk has been in contact with me regarding the query and i am yet to receive the final outcome. i have been receiving calls from collections saying i am owing and i have been explaining that there is a query pending as such i will not talk about the issue of owing them. i spoke to someone before 8am in the morning today and explained what is happening she said she will write notes, now i receive a call from the Itumeleng who refuses to give me his surname shouting at me that i am owing and that is why he is calling. i ask him to speak properly as he is shouting and he says that how he speak if i know him personally i will understand, firstly i don't have to know someone personally to know the person is being rude, his tone changed from the time he greeted to the time i told him i have a pending query. is it my fault that their department is taking time to resolve my query and again Nomthandazo has been saying she is sending emails to collections to tell them that there is a query however i have been getting numerous calls and i have been explaining myself. its so disappointing that i have been a loyal customer with Cell C for year and its has come to this. Itumeleng is extremely rude and i wonder how he works with people, the arrogance is a clear indication that there are normally no implication when they rude to customers. its a shame! i also work with customers and irrespective of the circumstance customer should be treated fairly. my only sin was to ask if the person i spoke to this morning didnt put notes? i an so angry on how this person spoke to me, its a shame that they keep such people. imagine being a customer that doesnt have a query and at that time you are unable to pay and you find such a person , he might even say its not our business that you have problems we what our money. sis i am disgusted of the treatment i have received. i will proceed to refer the query to the NCC since this is now becoming unbearable.
