Worst Service Ever!!

My boyfriend and I are existing Teljoy clients and we have been trying to add units since the 6th of April but their addon email address do not even reply to emails, I have been calling and online chatting with the consultants and they say we must start new applications...how do you do new Applications when you are an existing customers?

I sent an email again to addon on the 20th May 2020 and still nothing.i did an online enquiry, trying to call but no luck still. It is like it is a dead end .

We understand it's the lockdown and everything but your service is now very poor and you don't even treat existing clients accordingly.
