Cell C call centre is rude!

Cell C has a few call centre agents that are so rude to their loyal customers. My mother in law was called on the 26-02-2020 by Sipho Nqubeni and told my mother in law is due for an upgrade- She chose a certain Samsung phone and he told her that it would be send to her- She still has not received the phone.Yesterday 11-03-2020 I went with my mother in law to cell c in centurion mall to upgrade the same number as well as another number- K****tso Morekei assisted us and told us that the number Sipho has upgraded is still active and the phone is still being processed. As we phoned Cell c call centre we spoke to 4 different consultants-especially Nthabiseng who just dropped the call on us,after numerous people just to get through to Sipho Ngobeni- As K****tso spoke to Sipho to ask to reverse/cancel the order that he made so that we can redo the whole upgrade and get the phone in store- he was so rude and asked her why are we phoning again and being very disrespectful towards K****tso from cell c centurion. My mother in law has been a cell c customer for 15 years and this is the type of service she receives????? Her number that was questioned was ***. As told by K****tso we were not able to get the phone as it takes a while to cancel it from SIpho ( or that is what Sipho told her) now we would have to go in AGAIN in order to get the phone as soon as it has been dealt with. Thanks K****tso Morekei ( sorry if i misspelled your surname) for all the patience and assistance in this regard!! Cell C we are still waiting for the phone
