cell c disgusting customer experience

I went into the gateway store and i saw an upgrade i wanted to take , i was told that it is to early to upgrade my current contract however i had two options , take out a second line and when my current contract ends i can cancel and do a number change to retain my current number with the new contract . I was happy to take up the new line as they discussed . I contacted your call center yesterday regarding an upgrade. However, I got through an advisor who kept on asking for my ID number and Mobile number continuously as he was clearly not paying attention . no telephony skills and no call flow .This went on for a few minutes till I requested a manager . The advisor stated that he will get a manager to call me and note I only requested this because I was getting nowhere with this advisor .I was promised a manager however to date no one called back . I called again and spoke to another advisor from the New lines department who I felt very uncomfortable dealing with as he was asking me very sensitive questions " How much do i get paid before and after deductions " " Do I have any Kids? " Anyways he offered a deal and I said I will get back to him . Remember all i wanted was to take up a second line and wait for my current contract to finish and get a number change . I called back today and spoke to a few advisors who kept on transferring me from department to department and also transferred me to the prepaid department who can not even assist me with my contract . I always have this issue when I call in and request to speak to a manager. They are never available . I have been with CellC since 2014 if not longer and it's always a struggle to speak to senior people who never want to take a call . 2 advisors told me to SHUT UP and dropped the line , one person told me to **** OFF . I called again , Spoke to Bridget Pudikabekwa explained to her what had happened and i also asked to speak to a manager , after 1 hour and 15 odd minuted a managers comes on the line which is Lutendo Ratshilumela she did not even know what was going on which meant i had to explain again , I responded and said please get Siphiwe Msomi who was meant to take this call . I requested a complaint to be opened , I was told that it can not happen and i had to email to open up a complaint , i was shocked i went to the gateway branch and put my call on loudspeaker whilst one of the consultants was listening to how i was being treated and he was also shocked and appalled to the fact that the advisor did not want to open up a complaint . I waited 1 hour and 30 minutes eventually got through a TL Siphiwe Msomi . I told him about my experience , I also told him all I wanted was an upgrade. I asked him to open up a complaint and he did with ref number *** I spoke to Siphiwe Msomi right up until 1 hour and 59 minutes and he eventually CUT the call on me and did not have the decency to call me back . I find that very unprofessional and disgusting .
