Bad Service

I lost my phone and went to the cellc store in Mooirivier mall potchefstroom to go and do a contract sim swap for R116 the sales consultant that was helping me told me to produce ID and Proof of Res I told him I don't have a proof of res he must print it on the system he then disagreed and final went to ask the manager who agreed that the consultant who was helping me use the proof of res on the system, I only used a sim card for the April month till the Sim card said No Sim on the phone today I went in store to do another sim swap instead of the sales consultant helping me with the NO SIM that's not working for what I don't know even JC Du Toit who was helping me couldn't tell me or help me instead he told me to call customer care to strart with, with which phone because my phone hasn't been working for over two weeks I told him it's his responsibility to call Technical support/Cellc but he refused and told me to call I mean my phone it's not at faulty your Cellc Sim card it's Faulty I asked him how many times am I going to do a sim swap and pay for it he told as many times as I can so to me that's in competency problem with the Cellc in potchefstroom there is always new faces who doesn't know what their doing including the Manager himself I am extremely angry with the service I got because I am not going to pay for something that I don't know what happened with it If cellc can't tell me what's wrong with my sim card who must tell me? I am extremely furious I feel like taking my business somewhere else because of people including the manager who don't know what they doing, your staff and your managers needs alot of training because they are so blank. Cellc Potchefstroom won't get anywhere hence they will change staff everyday because of lack of Knowledge and incompetence.
