Horrible service- New customer

Absolute horrible service from this fiber provider. No contact center for escalations, no follow up. I am a new customer, paying my ISP, Mweb with no fibre box installed. I am waiting going on 3 weeks for them to send a technician from Openserve to fit my fibre box and have been on the Mweb call center everyday with no success. Absolute waste of time and horrible service. Going to cancel this service that i am not even receiving by the end of today. Openserve escalations team are also useless, they call you once and then never again. When you try to contact them back it goes to voicemail everytime.
