Terrible Service

I ported from one cell phone network to Telkom Mobile in August. After activation, i could not identify the names or numbers of people who call me. (whenever someone calls me, there appears 'unidentified caller' on the screen) on the 8th or 10th of August i contacted Telkom Mobile call center to report this, and the person assisting me failed to solve the problem and said she would transfer the matter to a specialized department. <br> <br> it is almost two months now and my problem is not resolved. every time i call to find out if there is any progress, i am given the same response - (the matter was transferred to another department and they will contact you as soon as possible) this happened on about 5 occasions and not once did any of them get back to me.<br> <br> This has been a frustration in my professional capacity, as i am always required to respond to the calls i have missed, and this is not possible since i am not able to identify them. to solve this problem, i tried to port back to my previous network and i failed twice because the previous network say that Telkom Mobile seem to be refusing to release my number.<br> <br> I do not know what else to do<br> <br> Please help
