Telkom Mobile problems and refunds

I had a problem in 2015 when Telkom billed me double , my contract and another contract which was not mine. After going in to their office 3 times (only 1 in Polokwane with mostly 2 people whom can help you with waiting cues of between 15-60 min) and 19 call follow-ups with 6 email replies over 3 months I was credited. They accidentally disconnected both my contract and the other contract and I was offline for 2 weeks before the could reconnect me ( another 6 calls, 2 emails and 2 trips to their office). When upgrading came in May 2017, I was informed that the system shows that the contract can only be renewed in Nov 2017. Over a month ,3 Trips, 2 emails and 7 phone calls later with waiting for Telkom HQ to retrieve the original Invoice ( the one I had was fade in places) the upgrade was done. They still erroneously deducted +/- R2200 from my account for early upgrade and then the battle for refund started. After many phone calls and visits they admitted the error and I am still waiting for the refund. Telkom - Best rates and deals, worse after sales.
