Telkom service non-existant

Good morning I have a complaint against TELKOM SA pertaining to the fact that I cannot receive calls on my cell phone since changing to Telkom Mobile. My number is ********** and was ported from FNB to TELKOM MOBILE ±18 months ago. I am involved with a disaster relief company in Texas USA, they are not able to contact me on my number, and the message that they get is “This number does not exist.” This inconvenience is resulting in a loss of income I have taken the matter up with Telkom approximately 3 to 4 months ago and contrary to all the text messages that Telkom has sent me that the problem has been resolved I still cannot receive calls from numbers from other service providers. I consider this a breach of contract from Telkom, Telkom is unable to provide me with the service that the contract specify. I need Telkom to come to the party as follows: 1. To fix the problem before 19 August 2018. 2. If the problem is not fixed by that date, I consider the contract to be nullified by Telkom. 3. This will enable me to consider other possibilities. Thank you Isak Haarhoff **********
