Unsatisfied client with One2one

On the 12th December 2019 I called in for the 12th time to cancel my one2one contract and to have my number and my wife's number changed back to prepaid as we wabt to port our numbers to Telkom. I spoke to Tozama who was the consultant and she assured me that it will be done in 72hours and I spoke her her Team leader BLANCE is her name and she assured me not to worry it will be done. Today 12 February 2020 and its still not done. I'm from the Markham store and they told me again it will be done within 72 hours. Can the Ombudsman please help as this is really very bad service and I think alot of people are very frustrated with this matter
