Horrible service

About 3 weeks ago I paid for an installation to be done at my place. When the people came they told me that the power was not strong enough and I had to get an electrician. Instead of doing that I requested a refund and I was told I’m going to get it. It’s been so long now and I’ve been waiting for that refund. The people on the line told me it has been sent but nothing has reflected on my account and it’s been days now. I want my money back. If this is the service ikeja offers to the people i regret even considering to have you install my Wi-Fi.
