Absolutely Pathetic, Horrible Customer Service Experience

Have just had the most horrible service experience ever.

We have been a Telkom client since 2015. We recently upgraded our line from a 4mb line to an 8mb line.

We were told an sms was going to be sent to confirm when this would happen and no sms was ever received. Over and above that, we received a bill stating some horrible amount.

When calling to inquire as to why the bill is the way it is we were told that when accepting the upgraded line (no sms received) that we would need to pay a month in advance which was never told to us! We were then NOT ALLOWED AT ALL to speak to a supervisor which seems to be a common occurrence.

How is it that this company can always get away with blind siding us and have nothing ever happen to them???? EVER!

Absolutely disgusted in the service.
