No After Sales S****s

I did an upgrade on the 01/08/2017 with an MTN consultant online, after my cellphone was ****** from me. The sales consultant Annelise Stevens assisted me swiftly and told me that the time frame for delivery of the handset is 3-5 working days. The 4th working day passed and I called MTN again, to ask when I'll receive my upgrade and it was explained to me that they have issues with the courier company, because they changed from RTT to DSV and that is causing a delay which might take 5-10 working days from the date of my upgrade before my cellphone is delivered. I followed up again on the 8th working day and spoke to Silindile Mdubo and this Team Leader told me that my handset has been finalized and DSV should have my package. She transferred me to DSV after asking her to conference the conversation so that we can all be informed where the fault is and she just transferred me. DSV explained that they have no record of my information so they dont have the package. Later in the day I spoke to a lady by the name of Kim Basson. She was really upfront and straight to the point and she told me that the cellphone will be with DSV today on the 11th working day. MTN has no form of after sales service, they really broke my trust and the only reason why Im still continuing with them is because i need a cell phone. They never do follow ups and all the time and money I've wasted contacting them should result in a credit to my account or some sort of compensation to my MTN account. Can some one please call or e-mail me with some constructive feedback to tell me when I shall receive my cellphone, because this is unacceptable for an international company to excess SLA's.
