Poor customer service

I bought an electricity from the company via their USSD code and the transaction went through but did not receive a token voucher and it was on the 14th and the following day I made a call them and they said they will log a query and escalate it to team leaders and other department. On Monday I made a follow up and they said they will escalate it again. I kept calling them on the status of my query and they said they will escalate until to date. I`m very fed-up on of their poor service and won`t recommend anyone to their service they provide. They don`t care the situation on your side because without electricity everything come to stand still.
