Teljoy lack of communication

Teljoy collected a faulty television from us on the 4th of January and ensured us the television would be ready within 3 days and if not a loan would be provided. No communication from their side since collection of the television. Still waiting either for our television or for the loan and when phoning or sending emails or WhatsApps they simply drop the call or don't reply. Very bad communication. Before this we were happy with the services provided but now it seems it is better to just cut them out of the equation all together if this is how they handle problems
