Mpr Mobile difficult provider

MPR Mobile.i didnt have a good experience with their customer service /care. My Stk phone telephone sales was bought on contract in sept 2017 .started paying october 2017 ,8months later the phone was broken.batterie got swollen. Customer service doesnt want to replace it before according to their policy a screen that is broken isnt garanteed.i never had any contract. They want me to carry on with installment while i cant use the phone nor being repaired. So so disappointed. Be careful with online.or telephone sales. Request the contract before any decisions.
