Extremely poor customer service and network connection issues

Extremely poor customer service and network connection issues. Since joining Rain 5G a couple of weeks ago I have spent hours on end trying to get hold of their support centre to get my connectivity issues resolved. Initially they had a number to phone, but no one answered. Then I tried the online chat which you have to queue for hours on end and hope you do not get disconnected and once you get hold of am agent they are unable to assist or give you an update on your issue - other than that is with head office? It is now been almost 2 weeks that I have been having poor connectivity, specifically with voice calls/skype meetings. This is affecting my work and is extremely frustrating. I have even tried upgrading to their premium service, which if it was ever done (?) made no difference. Since this morning there is not even an online chat function anymore? If it was not for the lockdown, I would have already left them. Pathetic!
