Extremely pathetic service

I has a neotel subscription a few months ago. The sales person from the call centre checked my coverage for the neotel ****le and informed me that I have full coverage. I had the **** for two days and saw it was not working. I simultaneously spoke to the sales person who he himself sent a request for technical support to contact me however I did not receive a call. I went directly to the neotel store and a sales person himself doesn't seem to know what is going on. He plugs the ****le n says its working. Neotel is situated in that damn place so they will get perfect coverage. I had to make another trip to the store and a different sales person assisted me ans assured me that I will be reimbursed for funds taken off my account, 2 days ago I received a sms to say I need to make payment. I'm sending emails to both of these sales people however still no reply. Its been a month now not even the accounts department called me. I had given my work number due to not being able to use my phone during working hours. Neotel has a don't care attitude towards customers. I don't think that they understand the importance of customer service, I would not even advice customers to join the network.
