Terrible service

I am truly unhappy with the services received from Supersonic. On Friday I have asked Supersonic to approve the change of address on RAM Couriers. Yesterday I followed up and they told me that they have advised RAM on the change of address. This morning I received an SMS stating that they are delivering to the old address, I immediately send Supersonic an WhatsApp, they advised that they will inform the agent working with my order of the address. I phoned RAM after receiving a call from their delivery guy, they informed me that Supersonic has still not approved the change of address. It has been 5 working days since I requested the change of Address and 7 working days since placing my order. In the meantime I am sitting without internet waiting for someone to do their job properly. I would also like to find out since I have paid in full for February and still haven't received my router and it's already the 6th of the month, what will be done for the days I'm being charge for something I can't make use of. I want to cancel the services but keep getting an error
