GIVE MY DEPOSIT BAC****!!!!

Hell, where do I start...I have been struggling to get my deposit back from Telkom and yet I have been receiving invoices on a service that I do not use. This is unacceptable because I have been struggling for a while now. The agent at the walk-in centre logged calls and according to him, the only feedback he received was negative. However the very first call he logged read that the deposit of R700 will be released on the 18th March 2020. I already spoke to the guys on Facebook in February already and THEY have given me a reference number and said that one of the credit personnel will be in contact with me....well it is March and I am still waiting for my money.... AND NO-ONE CALLED ME AS OF LATE. I cannot wait to finish the one contract I have with them so that I can move to another service provider.
