Pick n Pay bad customer care and service

Ordered online for delivery on the 26th March. A R2k+ amount was 'reserved' on my credit card, and then a bit later a payment of R1900 was taken from the card as well. Goods were only delivered on the 27th, which I can understand with the current situation. BUT, the reserved amount of R2k+ has still not been released back into my account after 10 days. This is unacceptable as we need the money for other costs. The call center and emails are a joke and get no response, and by the looks of the response from Pick n Pay on this platform it is a form message of no value. Yes they are stressed and short staffed because of the lockdown - but the rest of us are as stressed, and reliant on them to do their essential jobs properly. Lockdown is not an excuse for bad service in an 'essential' service
