Use PayU if you want to loose customers

I tried to make a purchase on the MySubs website, of which the payment options are managed by PayU on 12 Nov 2015. My purchase did not want to go through. I contacted MySubs and they advised my to contact my bank. I contacted my bank, and they told me from their side there is no reason why the payment should not go through. I asked MySubs to please investigate, and I have also sent an e-mail to PayU on the e-mail they provided with the message to ask them to check this out. This is almost a month ago, and guess what? No-one has contacted me, or even bothered to acknowledge my e-mail, and I am still not able to make a purchase on this website. This is atrocious customer service! And one has to ask yourself - if this was your business, would you use them if you loose customers because they are unable to make purchases? I would definitely not! Especially in the current economic climate - their systems are clearly not working properly and they ignore your customers when they need help! Nice one!!!
