I am attending sterling seminar at sterling daman resort on 23/01/2015, based on that sterling offer to me 2 n/3 d free hotel package anywhere in india in sterling resorts.
Based on that i got free voucher on 11/02/2016 from mr. Shahnawaz qureshi (Shahnawaz. [protected]@sterlingholidays.com) and on 2/05/16 i claimed (Claim id no. Is[protected]. And i got response from sterling after 2 days from i claimed.
As per this mail which gift voucher which i got through mail, it’s not valid due to issuing authority stamp is not available on this.
Based on this mail, i call to sterling ahmedabad branch, on that time ahmedabad branch person giving me assurity, they send to me another valid gift voucher on my contact address within 2 days. But till date i am not receiving any voucher from the sterling. I am continues taking follow up regarding this on phone no. [protected] of sterling ahmedabad branch, but nothing result i get & from now last 3 days they are not picking my phone also.
I call 2 times on sterling toll free no. Also, but same thing happen their also. They said to wait & after some time our phone will disconnected. I also mail this issue to 'online. [protected]@sterlingholidays.com' but from their also i did not get any answer.
So i am not getting any satisfactory answer from any one of sterling.
If you people not want to give any reservation against free voucher to customer, then why you offer to them.
When your marketing person explain to us, on that time they told us very big thing about sterling, but when we said first we take experience of sterling then we will decide on that time they behave like we done something major crime.
After too many follow up i got my voucher by mail from shahnawaz quereshi (Shahnawaz. [protected]@sterlingholidays.com). And when i claimed then this issue is raised by you.
If this type experience we get from sterling then, how we believe on sterling & how we think to take membership. So pls. I request to you very first try to change your marketing person behavior & committed on your statement. Do that which you said to customer.
So kindly look in this matter & provide me my gift voucher.
