Bad customer service

Home choice is by far the worse company with the most poor Customer service ever. The customer services agents a rude and have no respect for their clients. My Dad whose 62 has an account and has been calling to query this account balance statement but his been given the run around. His initial opening balance and what is being reflected now are 2 different. The invoice which he received when his package was delivered and what his been told are different. On the invoice and when the package was begin purchased do not match monthly payments and contract terms are different also. His also being told of monthly interest fees are been added into the outstanding balance monthly. which covers for retrenchment my Dad is a pensioner! When Sibongile was asked if that this was ever explained to Dad that they'll be monthly interest added she said she did not know. I requested for the call recording she advised that feedback will be provided on the 19th. We called yesterday requesting for feedback from the team leader as advised by Sibongile, but we were put on hold and hanged up on numerous times 1st person was Phumeza, After having to relate the query again to 3 different agents who all dropped the call after more than 30mins. its costing us money to be calling in everyday and not receiving any positive feedback. May some one call us back to resolve this matter
