BAD SERVICE

Hi TFG, could you please assist me with a refund, I purchased a cellphone online on the hi website on the 11th of February and I then requested to cancel the order the following day as I urgently needed a new phone and the delivery was going to take long, I called hi and they assured me that the number *** ********** has been cancelled and I will be refunded, that was on the 12 and the cellphone was not charged in my account at the time, on the 13th I was still not refunded and I decided to go to a hi store on Jabulani mall and they asked to call the call centre, tha lady that I spoke did the same thing, promise that I will be cancelled and I will a refund, 14th, still no refund, today is the 15th, still no refund and no cellphone.
