Poor service - poor wifi lte connection

I have signed a contract for my wifi- lte middle of last month, everything worked perfectly as of the 01st of June I have been having issues with the connection and notification that appears to say no internet connection try restarting the router. I have made contact with the call center since the 1st of June to date this has not been resolved. i am paying a monthly fee to telkom for a service I should be able to use it is now 3 days into the month and I am unable to use what I am paying for with no assistance from Telkom yet you are quick to debit my account and offer no after service. Highly frustrated with telkom and will never use them again.
