No network covarage all week no explanation

<p>I have been out of signal for a week now and i have called Cell C and i was advised that my sim card had expired and has deregistered itself from the network I have to do a sim swop which I did do at the Pavilion Cell C store the 27th of July at 18:30 and was told that it would take 4 hours for it to be back to normal. it is the 28th now and i still cannot make or recieve calls or use mobile data on my ********** 041 number, which means that nothing has changed after i did the sim swop. i called again from another mobile number to cell c and the consultant advised me that she needs to load data for my line for her to be able to fix my line but she doesnt see anything wrong and after she had loaded data it would be fixed. After she loaded the data i still had the same problem i cant make or recieve calls i cannot use mobile data. I called Cell C again another consultant says i should do a sim swop for my line to be able to recieve and make calls, which i do not understand because just yesterday i paid R150 to do a sim swop because its frustraing having a phone but no network coverage at all. I anm stressed and dissapointed at the service that i am rwecieving because i am constantly told that theres no problem with my line yet i do not have network coverage. someone please help ASAP</p>
