**** to a client

I have an exisiting Telkom data contract. Mondo contacter me to upgrade which I did, they confirmed that this was an upgrade to my existing plan and my cell nr will remain unchanged however they will deliver me a new sim card. After process was finalised they called me back amd said I must contact telkom to cancel. Now i received the sim and it is a totally different cell nr. Since their calls are recorded which telecoms ombuds can I refer this to and seek legal advise to take this further and let the public know. I also need the call recording. Why lie for a sale or commission this creates a bad reputation for you and the company.
