Bad service from vodacom

Very bad thus far. On Sunday 20/09/2020, I went online to order home fiber. I battled to complete the contract online, because myself and my husband has a joint bank account, and according to vodacom this bank account does not belong to us. I have send proof of the banking details as well as my and my husband copy of ID. Till now nothing has been sorted out and no one in getting back to me. I asked for the sales agent to phone me back. As I think I should cancel the order, but still no one is getting back to me. If Vodacom does not want my business they can at least just come back to me and let me know so that I can go somewhere else.
