Pick n Pay online shopping non-delivery

We've never shopped online so our first experience of PnP online shopping (East London area) has been very disappointing. My husband and I are pensioners in the high risk category and we've waited 10 days for our online delivery which did not arrive yesterday on 7 April between 15h00 and 16h00 despite R850.00 being withdrawn from our cheque account on 6 April and paying a delivery fee of R60.00. We've tried unsuccessfully to contact the call centre and there has been no communication from PnP to explain the delay or to arrange another delivery time. We understand that there is a high demand, however, we expect PnP to communicate with its loyal customers - we participate in smart shopper. At the very least they should contact us to make alternate arrangements. They have our contact details. Beware other online customers ... you may also be let down by PnP!
