Highly ****ed off

Hi I started using rain last year and in the beginning I never had any issues, ever since lockdown started service became ****pier and ****pier. We were away for 2 weeks and never used the service when we got home it was disconnected. The 2nd July I sent an email and immediately a lady by the name of Dipau Hans emailed to assist me. Within seconds it started working as she reconnected us to the tower. After the call was ended it started again and I emailed her but this time no response received. I logged a complaint on the 3rd with reference ***, still no call back within 48 hours I logged another complaint on 5 July with reference ***, still no call back or even an email. Then my last complaint logged on 7 july with reference ***. I'm so fed up and want to cancel as this is a waste of my hard earned money. Problem is if nobody is answering my emails who do I cancel this **** service with????
