Telangana Southern Power Distribution Company [TSSPDCL] — Three phase Electrical meter burnt out thrice in a year

The three phase Electrical meter in our unit has burnt down thrice in the last one year and we've been made to pay 2850 each time to replace with new meter even when it isn't our fault it's burning out. There are regular voltage fluctuations in the Balanagar area and this could be a reason or the meters you'll are providing are of poor quality. I request the current meter which is burnt out be checked to find the cause and also the cost of the last two meters be refunded as they are in their warranty period
