Telkom Abuse

We took out a contract (some time ago) while the signal was good. Then the signal deteriorated, so they installed a booster. The booster broke and Telkom has refused to replace the booster stating that it is for our account (approx. R14000)!!Seen as our contracts are expired and are now month to month, we decided to move service providers by migrating our numbers to MTN. MTN get a call from Telkom who are now REFUSING to move contracts. When we originally took out the contracts we had to put a R20 000.00 deposit down. What this means is that we have to cancel our contracts with Telkom and move to month to month basis at which point we can only then migrate to MTN. That's 60 days of no calls - no business. How much is 60 days without being able to do business going to cost us???? How are they able to get away with this?? Telkom is appalling
