Customer Service is poor

Dear Cell C For a company that is in dire financial situation you really need to step up when it comes to customer service, this should be non-negotiable at this stage. After my contract came to an end 9 of June, from the 10th I took a month on month contract with Cell C because I’m nice and I’m loyal. My bill on contract was about R1100 then on month on month its skyrocketed to R2519.03. Two strange amounts were deducted, on the 29th of June R1846 and on the 15th July it was R672, what the hell? I called and was told to follow up myself on the 19th of July by Nomthandozo Booi Ref ***. But what really frustrated me was that I ran out of data on the 17th, I then called Cell C to buy 12Gig, the consultant by the name of Ntombifuthi (poorly trained, she even asked me what colour is my app and weird stuffs) she asked me to hold while she wants to find out if I can buy data, I obliged, then she hanged up. After these frustrations i tried to buy data via your app, and got a message that you are experiencing issues with credit card, I should try again later. I then called cell C back at around 21:28 last night (17th), the consultant also poorly trained and inept advised me that the for R299 she will buy me 6Gig as opposed to 12Gig anytime and 7 night that I’m seeing on the app. I have two month on month contract with you guys while I wait for iPhone 11 later this year I’m fed up to the point that I want to cancel. Please sort this mess
