Horrible service

I upgraded my vidacom contract in September. I did that online bit I smitakenly press new instead of upgrade. On the 07th of October I received two phones by different courier. I log a call for one to collected. A guy from Skynet collected the phone. Now I'm being charged for two lines. I have been calling begging them to assist since I return the phone. I'm told they haven't received the phone I returned. I struggled until I git help from skynet who forwarded the proof that it was returned on the 11 of Ictobet. To date nothing happened. They are so ***********. Horrible service. Each time I call I have to relate the whole story from the beginning. I will never recommend vodacom to anyone. They only interested in our money but the service is so poor.
