Hi, I have reached my tata sky account almost a year after on 1st May"16, after few hour of viewing I found the set top box is not working I have complained about the same on the same day and the service engineer visited my place after 4 days and he ratified my problem.After few hour on the same day I found the same problem persists.I again complained in the toll free No. and informed about my problem but the person I spoke to was very inefficient to handle my problem and assured me the service engineer will visit my place.
After waiting for a week I called up the the Kolkata Nodal officer's no. to escalate the issue but from the Nodal"s office my call was transferred to the technical team stating the Nodal has nothing to do with this, I feel ashamed to state you the fact that the person does not even understand simple english I categorically asked him if he understand Hindi even but he was a South Indian person and understand Tamil only.I thought I could finally made him understand my problem as he also assured me the service engineer will visit my place but till date its more than a month no one from tatasky has bothered to address my problem.
my concerns are appended below.
1.Who is going to compensate my recharge money ?
2.Why don't you have professional people who can handle queries in any language ?
3.Why don't you have a proper matrix to check whether the customer's issue has been resolved ?
4. What is the function of Nodal office ?( the same should be mentioned in the website)
I ensure not to recharge my tatasky any more, pathetic service.
