Poor customer service Domino's Cavalier Centre, Blue downs

Worst service ever! Not the first time. I placed online order. Order went through. Store delivered wrong pizzas to house. I actually had to go to store because they dont answer the telephones.... which totally defeated the purpose of online ordering. Upon arrival at store manager didn't believe me, even after showning messages. Note that I came to store with incorrect order, which was delivered to my house. The boxes clearly had a different address on it.... and still manager was convinced I selected wrong store when placing order.... how do you explain that. After much arguing and after driver came to verify that indeed he delivered those pizzas to my house, only then manage decided he will give me the right order.... 3hours later! Today, again I placed an online order. Order went through. Money was deducted from my account.... no delivery. Yet again it cost me driving to the branch. At the branch they refuse to give me my order, which I have proof of payment thereof.... needless to say im livid. Domino's management suggest I reorder and pay again..... another R246.70! In order to receive my order.... really? Am I expected to pay R500 for 2 pizzas and a jalapeno popper?.... seriously!? I was given a pizza to make me go away, with the promise to resolve tomorrow. I must reinterate that I have no faith in the resolution of this issue. Dominos has proven to not care about their customers. Im disgusted.
