Annoyed potential customer

On the 14/06 I app**** to have fibre installed at my house. Fast forward today I called to follow up and after waiting over 5 minutes on the phone my call was cut. Now I haven't even started business with you guys but already the taste in my mouth is starting to taste bitter. I'd switch providers but you guys already have my banking details... so what do I do now??? Are you coming to help me or should I cancel my bank card??
