Disgusted with Vodacom's service

I did an upgrade on Vodacom contact in Mar 17', after i had done the upgrade I noticed that i was being billed for 2 handsets. I immediately quired this and was told that I did an 'early upgrade' something that i was not aware of. I was told i will need to pay for the old handset for 3 months until the period of the contact is up. I was unhappy to pay for a phone I didn't even have anymore, but didn't really have an option. After June i followed up as that should have been the last payment. I was told that i was billed in arrears and that I would be one more month.

To cut a very long and painful story short, it is now 14 Nov 17', 8 moths later and i am still being billed and debited for 2 handsets. Vodacom is *****ing my hard earned money. Absolutely disgusting.
