REFUND...STILL NO RESOLUTION!!!

Wow such pathetic service its actually shocking!!!STILL NO RESOLUTION!!! I returned a device back to Vodacom on the 12th of February, I was debited from my bank account for a device that I don't have even though I called Vodacom to confirm that I wont be debited at the end of the month but guess what I was debited and I was told I will be refunded back into my bank account should the debit order go off on the 25th. To date I'm still getting my refund, have been communicating with Vodacom staff Zelda, Tsepho, Ashwyn, Pumi no joy what's so ever! Spoke to Ashwyn on Friday who was very professional and advised me that the refund will be done back into my bank account, received a call on Saturday from Pumi doing a follow up which I explained AGAIN I want the refund into bank account. Today Pumi calls again and she advised that they will deduct the money for the next payment which is absolutely BULL ****! Vodacom was quick enough to take money from my account and now its mission to get my money back. Spoke to Tulie just now who promised to come back to me within the next 15 minutes so lets see if she can get it right,If I don't receive a solution by today I will resort to 702 and a lovely letter to the CEO of Vodacom because I'm absolutely livered by the incompetence and atrocious service offered by Vodacom. P.S Apologies if the names are not spelt correctly.
