Non-commitment of refund-R854.84 for R299 contract

I signed on for a laptop contract with Vodacom in the Phoenix Plaza. The deal was for a 1 Gig TOP-UP data package at R299/pm. I was assisted by consultants Nobuhle and Yaseen. The account was incorrectly captured as an open line and I was charged R854.84 for August. I went into the store on Sunday 06/09/15 and was asked by Prelene(one of the managers) to return on 08/09/15 with my documents. That was the 2nd incident of unprofessionalism. On that day the 2nd store manager (Chaman) assured me that it was the consultants fault and I will be refunded an amount of R555.84 BY the end of September. It is Fri, Oct 2, I am yet to receive a refund. And my account was debited again this morning for the month of September. I called and spoke to Prelene at 9.43 and asked her to call me back with details and she did not! I had to call her back at 12.40pm to get a response. I am still waiting to be contacted by the store with details<br> I'm utterly disgusted at the non-commitment and disregard that the staff have towards sorting out this issue! It must be sorted by day end, even if cash reserves of the store is used!<br> Rest assured I will never deal with vodacom again after this contract ends!
