BAD SERVICE

So MBD keeps on messaging me to tell me I need to make an outstanding payment. I have been trying to contact them for so long but cannot get through to him. According to their voicemail, operating hours are 7.30am to 19:30pm. I have tried to call during these times! I then send a email as I want to make a payment but do not have the banking details (this is not given in the sms which doesn't make any sense). I then got another message (which I'm being charged for) and I call them around 11 am and i eventually get through to an agent named Kagiso. I tell Kagiso I'm going to make an EFT payment and he informs me that there will be additional charges should they sms me again before my payment reflects! I work late shift which is why I call from about 16:00pm onwards and he informs me that their hours are 7:30am to 16:00pm. So whose fault is it that your damn voicemail gives clients incorrect information and I've been calling like a maniac to get through in order to pay my account! Then also telling me I will be charged again and STILL no response to my email! This is super bad service and extremely frustrating. I refuse to pay any other additional charges added to my account. I have made the full payment today, Kagiso gave me the outstanding balance of r433.57 and I'm done! If you want people to pay their accounts then maybe you should be available during your operating hours and respond to their mails instead of sending useless messages.
