Telkom fibre is a *******!!

I received the worst service with my Fibre line. Signed up in Jan and got an annual increase in March. My service was suspended EVERY SINGLE month apparently for exceeding a credit limit set by Telkom themselves. Also got a Vas on my account that I tried to cancel 3 times with no avail despite internal "escalations". Now they want to charge me R3700 for early cancelation on a service that was a headache from the start. Not to mention their service line where retentions drops every call and billing transfers calls to other departments with no context. The lack of service is beyond frustrating and at the end of the day I think they owe me a refund for the premiums I have paid!!
