Worst company ever

This must be the worst company I have ever dealt with, 1st they deliver the incorrect device, then over charge me and offer a credit yet I still paid the full amount, they don't even have a direct line to their customer service team only a whatsapp line which is never monitored, onto of that their employees including their managers are rude and unhelpful....I recommend to rather use the network operators or even Teljoy and get a contract with them instead.
