Poor service from Cell C

My daughter has been attempting to upgrade contracts that is due for upgrade since Monday 23 Nov. This has unfortunately turned into an absolute nightmare as the consultant messed everything up in terms of matching up devices with specific contracts and delivery addresses and here we are on Thursday 26 Nov not being any closer to finalisation than on 23 Nov. Seriously,this is extremely poor service! She has logged numerous calls only to be transferred from one person to the next with no solution in sight.
