Bad service

I took out a wifi contract with telkom, just to realise after already paying the first installment that we have no coverage. This was checked twice with operator. Then I send back the router on my expense to head office of Mondeo. Where the router was missing in action for more than 2 months, in which I was billed a second installment. After using courier guy in Durban to personally track the router I was told it has to go through the finance department. After another 2 weeks of phoning daily I was told ok the account is cancelled. Just to get refunded less than half the amount without specifying how it was calculated. Then telkom customer care promised to sort this with his friend at the finance department. Still waiting for my money and and feedback. Unbelievable.
