Vodacom are rogues

I am utterly disappointed with Vodacom's service. My number has been blocked by them so that I fo not get through to any of their help lines apparently due to suspicion of ********** activity but no one from Vodacom has the decency of calling me to check why I have been making so many calls. My upgrade order ref *** Is still not received or resolved. There was an issue with the upgrade date being incorrect for *** as it was supposed to be due in July 2022 but dates were messed up when I underwent the COVID relief programme for 3 months from July to September. Thirdly I was over charged for two contracts ( *** and ***) where the contract end date was June 2022 but to date I am still being charged for the handset cost on those devices, urgent refund required on that. Lastly I was double debited for a vodacome voucher advance in September and October so a R200 refund is due to me as well. So many complaints and my number gets blocked without even trying to resolve them. That's clear cut THEFT to me.
