Poor service and no response to complaints

By farcthr worst service from panelbeaters. A month an nobody folliwed up on my complaint. Not all work quoted and paid for sorted, incorrectly sprayed, wiperd damaged and not working after replacing windscreen and all of this after they delayed and inconvenienced me due to poor internal communication . So tired of promises to phone me back - they never do. Would never recommend. Better ofg with back yard panelbeater - think service would be better anyway
