VERY BAD CUSTOMER SERVICE

I used to be a customer of Iconnect who unfortunately gave the domestic side of their business to Cell C and I am having extreme difficulty in trying to sort out my account. I have 2 accounts one in Cape Town and one in Sandton. They are mixing me up with another customer by the name of Linda Pita from Bryanston - I am being billed for her and they are telling me I am in arrears to the tune of R6,400 approximately and I have sent proof of payment to them showing that I am up to date with my payments which are debited on the 25th of the month. Yesterday they disconnected my line and I had to get a third party to intervene and request that they reconnect me. I am at my wits end as this has been an ongoing issue since they have taken over Iconnect who were so professional in that they provided me with a daily report as to my data usage. TODAY I WAS KEPT ON THE PHONE BY THEM FOR 45 MINUTES WITH NO RESOLUTION. Maybe its time to switch service provider.
