Simba Chips 125 g weighs less than 80 g

I bought a 125 gram packet of chips and when I got home I thought that it felt a bit light. I weighed it and to my disgust found that it did not even weigh 80 grams. I still have the unopened packet. I then e-mailed Simba as per the details on the packet but as I had not left a phone number, they rep**** asking for it. I duly sent my phone number but have yet to receive a reply/response from them.

If this is the way they treat the consumer, I for one will no longer buy Simba products.
