Review Less customer oriented and more sales driven

If an option is given to rate them on multiple areas I would rate them 3.5/ after sales and 2/ customer relation. I purchased a vacuum cleaner/air cleaner (Rainbow) in the first week of January 2021 on reference. The sales rep who demonstrated the equipment was good at his job and quite open to discuss on the past issues that the model had suffered, and overcome in the recent up-gradation.

The highlights of the equipment appear to be:
*expensive against its competitors
*attractive for long term ownership - 10yrs free servicing/warranty
*user-friendly and easy
*all-in-one
*robust and reliable

However, sometimes there is an element of surprise with any new purchase and as a customer one is prepared for it. The last highlight "robust and reliable" was partially making sense as an experience for me. Within the first month my equipment alarmed me with a funny sound at slow running speed, and it was distinctively bothering me at night when I wanted to run the air cleaner mode. It was noisy and loud and no amount of distraction could help ward off the nuisance whilst trying to sleep. Nevertheless, there was prompt attendance of the same gentleman who sold the piece to me on reporting the issue (through a video). He took it for inspection by his engineering folks and within a weeks time made the delivery. Subsequently, after the first use of the equipment it once again presented the humming sound from its motor. The same order of reporting>collection> delivery (after repairs) was followed 3 times more, totalling 4 such calls with the same issue, and no conclusive rectification for comfort.

Finally, when i couldn't take it anymore and felt the pang of monetary loss and disappointment, I decided to inform their senior management that i would like to cancel the sales and move on. As a last measure from their sales book, they offered to replace the machine and provide a new one, with juxtaposing my existing piece with 3 other new ones to allow their sales representative to witness the irreparable sound audible from my piece. Once the drill of sound comparison began, I didn't need to convince the spectators and there were less words exchanged.

Almost a week since the swap, I have used the newly substituted equipment twice and find that it is performing as demonstrated (silent in slow speed) with little worries of going back to the supplier. Will be providing an update on this review in case there is any further finding on my purchase.

A few things to watch out after my experience:
> make sure that you run your delivered piece alongside their demo one - especially at slow speed.
> record if there are funny sounds or other issues that are encountered.
> keep receipts and invoices.
> if possible and convenient - take the option of payment by instalments.
> early on, mention any issue on mail and directing it to their customer sales department.
> once you notice an problem, do not use the machine any longer and report immediately.
