Poor service!!! Worst ever in my life!!

Why does service have to be soo hard telkom? I app**** for a contact since last year however my order kept on going missing. I again app**** dec/jan and finally got approved receiving my device nearly 2 months later. Despite everything i kept my frustrations to myself. Now that i have the device, still nothing gets done. I still havent received my 100GB once off for 12 months promotion that was part of applying online, nor has my number been ported to my old number. Weeks later and nothing is done. After hours on the phone with different departments, Orders and cases logged, one blaming the other, systems that are slow....i cant deal with everything that is wrong here!!! I agree that your deals are competitive however i will rather pay 10 times more than to suffer like this. All i want is my 100gb to be loaded that is due to me and my number to be changed. Clearly this is beyond your service delivery!!! Should i go ahead and cancel?
