Bad service-Telkom

I've app**** for a LTE modem by the end of November. I had to follow up on the status of my application at the store to know that I had to pay a R700 deposit. After paying it, they gave me another case number on the 6th of December (which I also had to sort it out at the store) . Today is the 1st of January (2019) and nothing has happened. Tried to phone the customer care line to find out the status of my case, they basically told me that It was advisable for me to go again to the store where I had app**** for the modem. Went to the store on the 30th of December(2018) I was informed that this case was supposed to be solved and the consultant also mentioned that he opened another case - ********** 6(cc'd the manager of the store to escalate the problem) and promised me that telkom would get hold of me. I'm just extremely disappointed with the quality of their services and how they manage their client expectations.
