Charged for a phone we did not take

My Boyfriend had went in to MTN Cornubia to take a Contract for the P20 lite and Router Deal, however that Special was not linked to their systems , some IT problem apparently and they were waiting for IT to correct it. We waited for almost a week and their systems was still not sorted out. We then went of to Telkom and signed up the contract with them(Worked out much cheaper aswell). We went back to MTN ( about 3 shops away) and told them to please not follow through with that contract as we had already purchased the phone elsewhere due their incompetence and after waiting almost a week, (going into the store everyday). the sales consultant had assured my Boyfriend that he will not get billed, few days/weeks pass and now we are getting billed for a phone we don't have.

below is a ref numbers... we need this sorted out asap. REF-1- ********** 8513 QUERY **********

monies need to be refunded and we should not be charged any cancellation fees due to the error being on your side.

its really disappointing knowing that he was an avid MTN user. when he calls customer services they say the store needs to sort it out. he has been to the store this morning and still no one calls him back.

this had come extremely frustrating
