WORST SERVICE PROVIDER EVER!!!!!

I took out a contract a couple of months ago and they ported my number from MTN. Till today I am unable to ****ing receive phone calls from other service providers and some landline numbers. I have called several times and so called managers were to contact me and nothing happens. Promises are made and never delivered. I ****ing want Telkom to come and take their phone and SIM card and port me back to MTN. Does the directors of Telkom see to client services or do they don't care as well like there appointed manager. I have been patient long enough and will be in contact with the NCA to cancel this ****.<br>
