Cashback is about to die...Yeah!
This has become an extremely deceptive sales tactic, due to certain companies exploiting the practice, wholly for their advantage.
The idea originally had merit, but it appears some companies (ACER in particular), are taking advantage of it by doing everything in their power to stall or deny the cashback payment to deserving customers.
Personally, I posted my forms " Registered Mail", am still waiting for the cashback payment, hopefully it will eventually arrive.
If not, I have lots of supporting documents to prove I have followed the "Terms & Conditions", if they choose to deny my claim.
The bad news for the companies rorting this practice is that they are alienating many good customers, who like yourself will never buy products from them ever again.
