Communication

So I have been a Supersonic customer for a year now. At that stage you could communicate with them on whatsapp, call center or email. I have FLTE and last year I had numerous problems with the connection and with these problems would mostly spend more than an hour on the phone to the call center trying to fix these problems.

I am only in the country 3 months a year and I have paid my bills on time every month.

Today I asked my father to just upgrade my package for me to Uncapped. Giving him all the information he needs to upgrade it using the call center. I cannot afford to phone internationally and be on hold for an hour. Call center employees would not help him even though he explained the situation.

So I then tried to send an email and I get an automated response saying this is an unattended mailbox.

I tried to upgrade via whatsapp and they do not even have that option.

I can't login to the portal either because internationally I cannot receive the OTP.

So how am I supposed to communicate with this company taking my money every month?
