Terrible post-upgrade service & misinformation

Wish I could give a negative rating!!! My account was upgraded in July. from a 1GB plan to a 5GB plan. Before the upgrade was done I confirmed with the agent if I will be able to recharge airtime and data. He advised me to download the Cell C app, I will be able to do it there. This function is not working. I have to call into the call centre to load and increase my usage limit. Secondly, I see on my statement I have a plan & device cost of R215. This was not the amount the consultant said I would pay on a monthly basis. According to him my fee would be around R100 per month. Thirdly, there was a limit of R430 set on my account. I don't know who did this or where I approved of this limit. I want my account to be downgraded to what it was as the information regarding the upgrade that was supp**** to me was incorrect.
