Bad service

I've been with Vodacom as from day one, period, more than 30 years. Took out a new contract, changed my banking details March this year at Mall@Reds. Firstly, they notified me, that the first payment will still go through on my previous acc. My mistake, I transferred money, only the contract amount back from my new acc.to the old acc.which I was not going to use anymore. Debit order returned. I take responsibility for that. Then, they DID not deduct from the old acc.but from the new account. My contract stipulates R429-00 per month. First payment with the change of my contract, was R649-00. At this stage they deducted R1919-85 in total. Which exceeds the amounts owed to them March, R649-00 + 2 payments April and May for R429-00. Via, email, absolutely no joy. Sent their sms'es as proof, my contract, now suddenly it's too "blurry" they can't read my contract. Then, I added extra services according to them, that's why they deduct more monthly. Why then a written contract? No proof that I added ANY extra services. Friend of mine had an internal ***** sim swop on his phone, his account exceeded over R20-000. Forensic department would've came back to him, it's been 2 years!! I think it's absolutely pathetic. How many services are we paying for, whoever is using it, if you don't check your deducted debit orders????

PS I can't cope with all these automated emails and emails get returned due to a full inbox from their side. How do you run a company like that, suppose an email address given out as a communication method, then read and delete!
