Never been treated as a loyal cell c customer...................

I have never had the pleasure of saying that when i upgrade it has been a great experience, every two yeas its just a mess full of problems that is never corrected. I went to cell c kolonade today to upgrade, after the lady phoned to check my credit score they said i was behind on some of my contact payments, i told her no we pay by eft every moth fo the last 4 to 6 years! I corrected this two years ago when i upgraded yet it has not been done. She kind of judged me and said i reversed the payment that was debited, i told her no i did not. i don't like the process of upgrading and told her i will pay the payments that's behind knowing it is not behind. she told me its fine but it will only reflect after about 48 hours, this is where i started to have a huge problem with this upgrading process i told her to check for my payments on the 25 and 26 of September on both contracts as i am not behind on my payments . she did find both my payments however i still could not upgrade because my payment that was made on the 26 is still not reflecting on the system 9 days after the payment was made? wow. I left the store as i feel you cant say or do anything to proceed even after i have always paid more every month to cell c than i should. the only times i had problems paying is when cell c changed the payments, so that you couldn't pay via your number anymore! I may have a low credit score at the moment i have no shame in that but i do feel so disappointed as i feel your systems can confirm i have always made cell c a priory, yet you have never made feel like a happy loyal customer...............
