Vodacom does not respond

From last year I'm trying to move my debit order from FNB to Capitec. I went to 5 vodacom shops and filled the forms to give permission to move the debit order from one bank to the next. I also left an email last year on vodacom's page informing them about my problem. Till this day I had no response from vodacom. If my contract is finish with vodacom I'm changing to another provider. This is not the first time me and my familie are having problems with vodacom.
