Disappointment with all Vodacom Departments!!!

Vodacom just has bad customer service and their sales department just makes errors no one can assist with. I bought a double deal cellphones 2 years ago. Firstly I didn't get the colors I ordered or dual sim Phones. I asked for insurance on both devises and the lady still asked if the second phone number would be vodacom and what the number is, I gave her the number for insurance. To my disappointment I only found out when I took the phones in for repair that only one device has insurance. Then I called all departments no-one can assist. I asked for the recordings they still has not given it to me. I then found out that they have been charging me for an additional insurance for 6 months i asked if it is for the second device they said no its for the same device. They said they will process the refund for me within 7 days. I called after 3 weeks just to find out that the refund was never on my profile so now they said they will process it today. I am disappointed in their service. I am now paying for a second device that is broken which they refuse to fix even though this is their error. NEVER AGAIN!!
