BAD SERVICE AND DISAPPEARING OF DATA AND MONEY!!!!

It is absolute terrible how these cell companies can just ***** your money and data and then just shrug their shoulders. On the 30/06/2021 I recharged my cellc account with R220 to do a data roll over of more than 10GB with the cost of R205. On the 02/07 I realized that the data didn't roll over, but the R205 is off my account. I've been calling their call center since then to rectify this matter, but to no avail. Second lady I spoke to told me that I can't roll over promotional data, when asked but why is it giving me the option to roll it over, she couldn't answer me. My case just gets escalated and after 3 days I get a sms if I'm satisfied that they resolved my query. Nobody contacts me nothing. I've emailed them, called them, but still nothing. Today the lady tells me that back office says the data was rolled over and the case is closed. Now if I rolled over say 10GB of data plus my 2GB data for the month I should have 12GB of data, but no I had 2GB of data. It doesn't help to get angry at call centre personel as they are the punching bags of these big corporations. They can *****, treat you bad, what ever and nothing happens. I asked them to send me a detailed statement showing the roll over as well as to were that data went. They can't send it, but I must be happy to loose my money and data, because of their bad service. It looks like it's becoming more and more the norm in SA for giving bad service. and dealing with people that are not capable of assisting and solving problems.
