I raised a complaint regarding noneffective cooling of my split ac on 20th apr. A technician attended on 22nd. For every single thing he kept calling someone on his mobile and asking what to do. He checked and confirmed no gas leak, gas quantity full .The problem was of voltage fluctuation and we hadnt installed a stabiliser. That said and done after discussing over his mobile he said he had to change capister. So we allowed him to do it. After that when checked the ac started blowing hot air.He said it would cool in some time and said we had to get the gas filled now.He even collected advance payment for that and assured us it would be done next day.Net day they kept me waiting saying they were reaching in half an hour but never turnedup. In the evening they refused to come n when insisted they sent another technician at 8pm. He after checking said the compressor wasnt working .I requested for a day time to look for my receipt as it is within warranty period.
Next day i saw another technician working at my neighbours and happened to mention. He said he will have a look n fixed the problem saying it was just ainterchanged wire connection.Our ac compressor was working fine!!! When i called the service center to say i wont be getting any work done and they should refund me the advance they had collected, they refused to pay saying i had to get the compressor changed.Finally when i insisted that i dont want to get any work done further and they make a refund, they have raised a feedback saying " cust not willing to pay ".. They tried to change my perfectly working compressor, charged me for capistor which was also working fine, have been refusing to refund the advance collected since 3 days and use abusive language when insisted to refund.
Completely unacceptable from a reputed company as voltas !!!
