Rewards **** !!!?

On the 14/10/19 I received a phone call from Rewardsco on *** at 14h27. The gentleman asked me to confirm my ID number and then advised me that as I had been a customer with Vodacom for 16 years and had paid my accounts regularly all along, Vodacom are going to reward me with a Mecer laptop computer . He asked me to confirm my residential address and then said the “ reward” would be sent to me at that address before close of business on the 18th of October. Nothing has been received as of22 nd of October and I called the number from which he made the call. The automated reply advised me to contact them through the website www.Rewardsco which provided me with the number to contact them at *** At that number a lady called Tarran was able to tell me that whilst the reward was registered this was subsequently withdrawn. She was not able to give the reason for the withdrawal and suggested I contact Vodacom customer-care at 082 135 where the automated system directed me back to Rewardsco. TOTALLY UNACCEPTABLE SERVICE. Perhaps someone needed it more than I
