The worst nightmare of service

Our tower had problem during loadshedding,the power went off and we tried changing plugs but no luck. We realised it had a problem, we called customer service and explained what the problem was, the lady who was helping said she will pass on iur issue to the relevant party and took our details as she said they would call. Waited about 3 days for a call which we never got. Wrote an email explaining the problem and asking for a way forward. That let us nowhere too until we decided to log a ticket requesting cancelation as we were not getting any help. That got their attention as we got a call and like befire we explained what happened and asked for a way forward. The lady promised us that we would get the tower in 4 working days, today its a week later, no tower, no call, no email nothing. Worst of all my husband is working from home and we have been without wifi connection for about 2 weeks now. We dont know what to do anymore because even when we did ojr best trying to avoid all these stress by canceling they promised us what they failed to deliver.
