Customer service incompetency

I've had a query for the whole of August and no one is willing to help. I've had a contract with vodacom Nad paying 2 phones for yrs. I have been paying via Tha vodacom app if I have debit order challenges. For the month of July I've paid on the 30 July even today the payment haven't reflected on their side. I've went to my bank for payment confirmation letter and my bank even assisted me in send3an email to vodacom on the 5th even today all the consultant tell me that the can't locate the email and I have the proof of email with me given by my bank. All my phones are suspended I can MT even call my kids. Yesterday I went to mams mall to make payment. I had to go back home with my cash because there was nothing they could do to assist me in unblocking my phones even if I made payment because for them I didn't pay in July. I'm very frustrated
