Service Barrier

I bought a Netsurfer tablet from Pep Cell Alberton City at the beginning of last month. On Tuesday morning I put it on the charger, went to go bath, I returned to check the time and the tablet was very hot and the screen had cracked on the left side with ink collected there. I got to work and called the Pep Cell customer service and spoke to Verna. I explained to her what happened and she said I must take the tablet with the box and receipt to the store I bought it from and they will send it to get checked. I went to Pep Cell Alberton City and the manager Mastuntu must have really taken me for an idiot. 1st she insists its physical damage even though I explained what happened. Then she insisted that Verna doesn't know what she's talking about that it must be sent back to the manufacturer. then she said I must rather contact Netsurfer myself because she cant help. Then she tells me she contacted a technician at Netsurfer who checked on "the system" and confirmed that it is physical damage. What ******** is that!!! How dare she insult my intelligence like that!!? I again refused to leave the store until the tablet is taken, then she said I must pay 2hundred and odd rands just for the tablet to be checked and 5hundred and some odd rands for it to be fixed. I told her I will pay whatever it is she wants because I know I didn't break that tablet and Netsurfer will have to refund me. Then she said no actually I don't have to pay right now only once Netsurfer looks at it they will tell me what must be done. Now, this woman tried every angle to the point of treating me like an absolute idiot, trying to stop me from exercising my RIGHT, not privilege or favour, to lodge a claim of being sold a defective product. I expect a serious apology from Mastuntu, this woman really tested me.
