RAIN/HAIL/HELL!!

I got a simcard 22/07/2020 and i have not had a single moment of joy since. poor connectivity, work emails are constantly getting stuck, I can't even send a lousy whatsApp message in peace! before I got the sim I sent a Facebook messenger requesting assistance on getting started and coverage in my area and I have not received a response for over a month, I understand that the call centre is closed but you would think they would be better on other platforms... Eventually I had to get an I.T specialist to come to my house and check the connection quality which showed as good but it has been a NIGHTMARE. I requested assistance last night but after reading other comments I am definitely closing my contract! I thought I was the only one,clearly not! I hope I won't have any hassles cancelling as I see from other reviews that they are poor in that department as well
