Poor service!!!

I have a problem with my email for many months. I can't retrieve any older emails than 12/12/2023. When I phone them I get the same answer everytime. They tell me that my email is not activated. If I want to activate the account I must pay for it. I asked them numerous times to activate the account. They told me my email don't exist. I don't know how it is possible because I recieve email IF I have any signal. Most of the time the signal is so poor that I can't send of recieve any mail. I can't send any emails for my account. They told me today that I can't retrieve my email, because I delete my mails - which is not true. Each month I have to pay my account, but many days I don't even have a signal - only a round circle on my phone. Why do we choose Vodacom if they can't even answer your questions. This provider is getting worse and worse by the day. I will not commend them to any of my friends, their service is realy poor!!
