Still no help

Last week i reported that mrpmobile failed me as a customer.i have a contract with them for a prestigio tablet,the tablet is no longer working.i reported this through email and Nerasha said i should contact prestigio directly which i refused and reported this on hellopeter.Nerasha then contacted me and put me through prestigio,where i spoke to a guy who took my details and promised to call me back and he said the device will be collected and i will get a new one if it cant be fixed.its been a week and i haven't heard from them.so mrpmobile should make arrangements that i get a new device or they must just cancel my contract coz i am stuck now.for yhem to fix it,they will take up to 29 days.and they're still delaying to collect it.month end they take money from my account for a tablet that is dead.
