Tesco

Overcharged 80% of the time and unreliable deliveries.

Where do I begin? Always check your receipts!
On one of these shops, 2/3 of the products I ordered were unavailable, on other shops huge amounts were unavailable.
Regular promotion mistakes - always in Tesco's favour, never customers.
Overcharged something, 80% of the time, I'd say.
Deliveries made outside of a 2 hour time slot 3 out of 4 times.
One of these being over an hour later than the end time of the slot with no call or notification.
Cheated on promotional points
2/4 shops was short changed on points
Promotion invalidated because Tesco couldn't deliver goods advertised (4 weeks in a row)

CHECK YOUR RECIEPTS WITH CARE!!!
