Telkom Poor Service

On the 30h November 2018 I have requested an early cancellation of one of the cellphone contracts I have with Telkom. I have contacted the call centre on numerous occasions and have been told the matter will be resolved as soon as possible and that a consultant will be in contact with me. I have explained that I also work in a call centre and have provided them with the times to contact me and the number to be contacted on. Today is the 1 January 2019 and up until today the matter has still not be resolved. I am honestly upset with the poor service received and still the fact that the matter has still not been resolved.
