High bills and no assistance from *********** staff

I upgraded my device in May, a month early, and was quoted R1200 by the representative. However, my June bill showed a charge of R2929, and subsequent bills continued to show incorrect charges. Despite numerous attempts to resolve the issue, I've received conflicting information from various customer service representatives. The device's actual cost was supposed to be R400, but I've been charged an additional R2500. Due to the unresolved query, I withheld payment on the last bill and incurred R250 in late fees. The call center's unreliability, including dropped calls and unfulfilled callbacks, has added to my frustration. Given the poor experience, I regret renewing my contract with Telkom and would caution others about their services.
