The worst company ever

I can't decide for what to complain first so I will just write the facts. I came in this country 2 years and app**** for a mobile contract to them, declined cause I was not here for 3 months already. I app**** after 3 months, declined cause I didn't have credit records. I came back with credit card they asked me to pay the half of the price of the phone in advance! I denied and went to another company. Although, I am buying from them every month prepaid data. With a fast calculation I have given to them up to now around 10.000 rant. I app**** now for a contract for data home -130 rand per month for 2 years they declined me cause my passport will be expired 2 months before their contract! Obviously my fault for paying them money for so long! They have no respect for foreigners. Plus, to all of these all, ALL, the times they didn't even once inform me back for the situation, it was always me running to them n them to blame their colleagues!
