Bad bad vodacom service

I phoned in February and ask if I am due for an upgrade on my second number. The lady informed me that I am. I ask for a deal on P20lite blue data. The lady inform me they have a special now for flexi 165 and 2Gb data I ask her is it 2Gb data and she said yes I also ask if the line is closed and she said yes. Ok later I check on my sistem and saw that my 2Gb wasnt loaded. I phoned and was inform that maybe the lady will still activate the data the first I must just phone back the first when it is not. The 3rd I phone because my data wasnt activated. The lady activated. Okay now I get my statement double the amount I pay each month. I phone and spoken to a nice lady explaining to me everything. She put me threw to the upgrades dept the lady said that the supervisor just want to go and listen to the phonecall. Christina phoned back to let me know that I wasn't inform right regarding that i still owe on the other device and the 2 devices is my p20 and the old device. Its a fault from theyre side. She also never explain about the insurance and on my bill I am being charge twice for insurance. And I was inform about 2GB for the month now I got 5Gb for 7 days. Also wrong info. On my previous account I never had insurance. So I told her why when I ask if I am due for a upgrade she said yes but never explaine about my previous device that I still owe. Because if I was inform that I am only due for ugrade June I would have done it then in June. Now Christina told me she will send the courier to come and fetch the phone. I told her I first want to speak to someone in vodacom and she got an attitude with me and told me that the phone needs to be collected now and she first have to see when I got the phone because if it's a month old she cant take it back. I told her yes but is it my fault if I was inform wrongly by her agent?? She said i must pay for both device vodacom rule or she will fetch the phone. I said I will let her now tuesday or wednesday then her attitude got even worse. Now why must I be punish for a agent mistake for not informing me I still need to pay the other device or the insurance wrongly on my account and the other amount on my account. Is it fair that I as a customer must pay for a agent that doesnt do her job right??? Don't customers also have rights??? Must I go to the consumer board??? Really why must i give my phone back for wrongly information. I allready spend over R200 for a screen protector and casing. Why must i face the consequences for someone that didnt do theyre job right. Why must I face the heat. What kind of customer service is this?? Am I the wrong one
