Tata Sky — Set top box is not receiving signal

Address:

Nashik, Maharashtra

My tata sky subscriber id is [protected]. I have Changed my set top box from mpeg2 to mpeg4 On 5th feb 2015. From that day my problems started.For two days it had a problem of software Downloading.then after doing so much calls to local Technician he came and changed receiver. Its fine it worked for 4-5 days. After that new problem started set top box is loosing signal every after 10-15 minutes. Weather is clear, no clouds, no rain, nothing still set top box is not receiving signal. After calling customer care they arranged technician visit on 15feb2015, WO:GP3A5O2. but no technician visited. After calling him he said that he will come in evening but still he has no seriousness towards customer complaint.he didnt came not even gave feedback. Now i am fed up of calling boring customer care IVR. It takes 15-20 minutes to put your complaint.just want to throw Set top box out.very poor service.
