Unipin pin purchased from Spar and I get an error

I purchased a unipin pin from spar last night and tried to retrieve my token via ussd and sms but every time I try I get an error and nothing happens. I have called blue label and they say that the only thing that they can do is give me the email contact for unipin. I have tried a few times the whole of today and have not received any response to have my problem solved. The customer service for this company is pathetic as there is no way to get a hold of anyone after hours. Now my family has to be without lights for the whole day. I am really not impressed
