Airconditioning

I bought and installed myself a air con and it had a gas leak I phoned Pretoria verkoeling and they came to repair the leak they did not even open my inside unit thy said the nuts outside was tightened wrong and i believed them and paid them the money.After the vacation i found that the aircon was stil not working again and phoned pretoria verkoeling they said they wil come and fix it and it never happend after 2 weeks of calling i just gave up and called Armstrong air conditioning at *** will definitely recommend them to everybody. Please do not use pretoria verkoeling.
