Poor Cell C service regarding phone

Herewith point form history of problems:<br> 1 - Upgrade wife's contract. done around March 2015 - to Samsung Galaxy S5<br> 2 - Phone *******s the sim card at which point cant access network - no calls no sms's<br> 3- Phone has been in to Cell C and repair center 4 times each resulting in sim swap and software upgrade<br> 4 - Said fix lasts between 1 and 2 months then problem starts again.<br> 5 - The 5th occurrence (end Sept 2015) of same problem has happened and all i get told is to follow procedure and send phone in again for another 3 - 4 weeks all while I am still paying the contract. No offer for loan unit what so ever from Cell C.<br> 6 - Manager wont make effort to arrange meeting with area manager or Samsung rep<br> 7 - Manager says they must convince Samsung to swap out phone - yet i am not Samsung client, i am cell c, they must sort my issue out first then deal with Samsung<br> 8 - It appears as Cell C don't care about the client. I am trying to obtain contact details of someone higher up that can actually make a decision to the benefit of the client.<br> 9 - Cell C service and client treatment is pathetic and useless - Never again
