Sony India — Mobile phone sony xperia c4

From the day (20th July-2015) I bought Sony Xperia C4 has been heating up after using it for more than 10 min on call and whenever I browse it heats in less than 10 min. At that time shopkeeper told me that we are down loading lot many apps so it is working very fast and that is why it is catching up temperature. In normal use it will not heat up.
Electronic thermometer was reading 43 deg Celsius after 10 min o[censored]se. I'm afraid that it may blast sometime and injure me. I had been to service center three times before and all the time they claimed that they did something now it should be OK. But status is same. This time on 2nd Nov-2015 I left my phone in service center (job sheet attached) and asked them call me when it is fixed. Till date there is no response from the service center.
This the responsibility of Sony company to provide safe device to the customer and since I am using this phone I start to have skin problem also.
I humble request the company to fix the phone for its heating problem or provide proper compensation for same. I am expecting response in coming 7 days from now otherwise I will be forced to launch my complaint in consumer forum for justice.
