Vodacom ***** and ****s

I sent an email to Vodacom ***** already a week ago no reply. ********** signature on a contract expired to change it to month to month data subscription. I took it up with the store and they stated we using it 1gb data is nothing now a days and who still uses sms. We have been paying for a contract we thought is changed to prepaid in 2019 already and we have been buying prepaid all the time only to find the signature on this document is not the account holders. They also upgraded 2 numbers on the same day and few minutes after each other the one number is no longer in use and doesn't even have a device any longer. Be careful of contracts before you sign. The store is manager is really trying to help but he also is trying to cover up for their non disclosure. BE CAREFUL
