Worst Customer Service!!!

We recently had the unpleasant experience of subscribing to Supersonic, as they are the preferred supplier in our estate. As new customers you would expect to receive nothing but the best service especially when your services comes highly recommended. You are fast to deduct our money via debit order, but we have not even been able to use the fibre internet! We have phoned numerous times, where we have to wait in excess of 45 minutes, but you never answer the phone calls. We comment on open tickets, to no avail. And your whatsapp line is a joke, no reply! How does one get hold of Supersonic to resolve issues??? You are undoubtedly the worst supplier that we ever had to deal with. Can someone urgently give attention to this matter! Why is it necessary to have to beg you the deliver some customer service, this is absolutely absurd!
