Worst Service Ever

I handed in my machine for a service on 26 March, I paid on 8 April. The first time I went in and checked on progress, they told me that they had assigned my payment to the wrong account. When I sent proof of payment and they confirmed everything was in order, they told me I would have my machine within 3 working days<br> <br> I have still not received my machine back<br> <br> I have been into the store in Canal Walk 3 times, they keep saying that a courier will deliver it to me<br> <br> But I haven't heard from anyone and am still waiting<br> <br> My father and I have private and corporate accounts with you, and are going to take my business elsewhere<br> <br> This is ridiculous
