Hongkong & Shanghai Banking Corporation [Hsbc] — No Drop box in Navi Mumbai

Address:

Mumbai City, Maharashtra, 40210

Sir,
I Mrs A A Dhillon, holding a credit card of your bank, would like to bring to your notice that there was just one drop box at Vashi, which also has been closed down about a year back. Now, there is not even a single drop box in Navi Mumbai. Though, your site gives a lot of drop box addresses, but those have been closed down years ago. I am also aware of other options of payment, but I choose this option . My request is to reopen the vashi drop box, or atleast one place in Navi mumbai.
Kindly inform me about the above matter please.
