Poor customer service received from the MTN team

Hi I took a data deal with MTN and the service that i am receiving from them is extremely disappointing. Firstly they staff are working from home due to Covid which is a good thing but they are rendering a poor service level to clients. I'm also in a customer service Job and i would have lost my job a long time if i gave my clients the service that i am receiving. I keep calling them on 135 and then being pushed to the cxd department as i would like to cxd my data deal, but have to hold on for hours, yes its a free call but some of us have actually jobs where we are office bound and don't have to sit on a call, I have so many messages with the team at 135 and keep getting told that they will get someone from the cxd department to call me but till date that has not happened, now I'm not one to complain but when my hard earn money is coming out due to a team rendering poor service, i now feel the need to be heard, so now i am paying for data that i am not using and no one at the MTN team, be it 135 or retentions or the CXD department gives a ****, i love how they say but mam thats not my department and push to the next after you tell them how long you have been querying this, so now when I'm typing this out guys its not a complaint about a department but on MTN as a whole because I'm not a departmental client but MTN's client. i deal with a lot of cellphone companies but never have a received such a perthitic laxity daisy service. The sad part is when you take the contract, they call you all the time, or if you due for a upgrade the will send out sms to remind you, yet when help is needed to get pushed around. MTN has now joined the ranks of a disgusting customer service level. I hope a lot of people see this and think twice of taking a contract with them. My ref number that i get is *** stating your query is opened but nothing else and still no call. All the ref numbers for my query and still no solution *** - follow up sms stating query closed but no one called and then just closed. *** - same story here, also sent an email to them.
