Pathetic service! Quick to take money but fail to refund

Absolute pathetic service. I have experienced issues with Mr Delivery on multiple occasions. It has been 2+ months and they have failed to refund me and even get back to me with feedback. I placed another order today, waited over 1 and half hours for the order to be collected by the driver, food gets to me ice cold and milkshakes diluted. Call Centre stated they will call back, however no one has had the decency to call me back.
