BAD CUSTOMER SERVICE

I have been seeking help to Rica my simcard since Tuesday. I have asked for assistance on what proof of address I need to provide if I am subletting. As you know the name of a sublease does not appear on the agreement and usually a letter is provided by the landlord with lease agreement and invoice for that month. I have not had a response from any of the agents who would get back to me within 24 - 48 hours. It's now 72 hours and I am unbale to use the service which they have already deducted for. Worst service during this time when they are busy pushing sales of their products. Surely you should be increasing customer support as such. Made a horrible decision actually. Fo****
