Disgusting attitude towards clients who used them several times

The most shocking service we have ever received!!!!! We have been booked for an appointment today at 9 am (we have 2 emails confirming this) to redo their job as it hasnt been done properly last time, up untill now no one has pitched up, when we called them they acted like they have no idea who we are (even though we have received a reminder email from their website), my husband had to take time off work, we had to organise doggy care to get the dog, we have a year old child who has to sleep ( they spray poison, so we need time to fan it so its safe to sleep) no one cares, after resending emails with confirmation the answer was ahhhh, we will come today, what time we dont know, what damn nonsense is that??????????First of all the job was done poorly other time ( they were also half an hour late without being bothered to notify us!!!) and today they didint even bother to pitch up!!!!And never mind we have paid over a thousand rand for 15 minutes of their time!!!!And they just say we will call you back and they never do!!!!
