Pest Control Specialist Sandton poor service

I have required the services of VIRENICE PEST CONTROL T/A PEST CONTROL SPECIALISTS SANDTON for a ****roach and ant problem in Northcliff. In the beginning everything went well, they came and treated my house and garden for ****rauches and ants. On there information it states that after a time have lapsed that they have to come back and do the treatment again. They did, all be it 2 days later than stipulated per their contract. After about 10 days of the treatment I saw a lot of action where the ****rauches seemed engergised and crawling all over. The second treatment were done as stated and I was not happy as the ****rauches never went away, are still there with the ants. Spend over R4500 with Pest Control Specialists Sandton with the same problem persisting. Very disappointed !!!
