Poor service delivery (M&B Cresent - Umhlanga)

I ordered 2 coffees and 2 ****ins from M&B Cresent Umhlanage. The order was supposed to be delivered in 40-50 minutes but actually took close to 2 hours to get delivered. I tried calling the store to speak to the manager, however this went to voice mail and Rob (the manager) requested we the customer dont leave messages but instead keep trying him (in the hopes we will reach him). Poor show Mugg and Bean.
