Incorrect upgrade and cancellation information

Worst worst service ever. First I was given incorrect information re a SIM upgrade. I logged a call, the investigation was done and complaint was resolved (or so I thought). The upgrade was to be reversed/cancelled, and I was told this could take up to 14 working days. It has now been 17 days, I follow-up and now I am told reversals can take up to 21 working days? From your Ts and Cs: Where a complaint is resolved in the complainants favour, a full and appropriate level of redress / corrective action will be offered to the complainant without delay. It is encouraged for complainants to approach the relevant entity of the Rewardsco Group with their concerns before escalating a complaint to the insurer/s and/or relevant external dispute resolution entity. I will be logging a complaint with the FAIS Ombudsman and will be cancelling my contract with MTN South Africa.
