Disgusted with cell C during lockdown!!!

So I was approached by a lady from cell C offering me a contract. I told her if I take out the contract they have to use my current Cell C number and convert it to the contract. She did so and upon delivery I will get 2 simcards. Which she explained to me, I must ignore the one theat comes with the fone and just use the other one seperately packaged, which contains the number had. So now, after 2months I got a huge bill. When I querried about it they said I have 2 contracts, thus the one sim she said to ignore is a data contract sim. I do not want, have not used or even activated that sim. When I phoned again they told me I should pay the full amount for my phone to be re-activated. After paying the full amount they just say I must wait till after lockdown because they blocked the account and can only be unlocked by their accounts department who only start working after lockdown. I am livid and dissapointed and disgusted that they treat loyal customers like this and in the midst of a national crisis!! Now i cant use the number that ive been using for more than 10 years, my primary means of communication, till after lockdown even though I paid the full amount. I'm disgusted with cell c
