Cancellation of contraact and refund of premiums paid

I struggled since Feb 2017 to get a contract for a Wi-Fi ****le cancelled and have the premiums I paid refunded to me. After several phone calls, and toing and froing between Vodacom and Mondo Mobile, Roland at Mondo Mobile eventually assisted me facilitate the cancellation and refund process, and has assured me that I will receive my refund with 3-5 working days from today. He returned my call promptly (I had left a message with Nicole) and called me back in the time promised with the desired answers and a definite timeline and reference numbers. I wish I had got through to Roland the very first time I had called. Thank you very much for the prompt assistance, Roland, it is sincerely appreciated.
