Poor fiber Network and customer service

About 8 days ago I made a ticket complaining about my 50mb fiber. Network is not working like fiber should and have been complaining previously also, left on their "24hr" whatsapp messages with no response. Someone called me 6 days ago he said he **** changes to my router then asked me when can they phone me back to confirm if my network is fine...we agreed on 2days later. This is now 4days later, my network is still not fiber worth and i still not received a phone call to check up on my network. I wouldn't recommend them as their customer support don't hive support and you don't get what you pay for. Will be ending my service very soon if herotel don't step up! I have had issues with them previously as well. 3yrs ago and the service still bad! Thought by now they would have improved.
